- After receiving a ton of comments about Surface Shield on my review video of Fluid Film two years ago, I set out to find the best automotive undercoating on the market today. I tested both of these lanolin-based products over a two year period to see how they would hold up. I was absolutely blown away by the results!

I've been fluid filming my truck for 8 years here in MI. So far no rust. It really works.
Good to know, thanks for chiming in.
I'm also in Michigan and am looking to rust-proof my 1986 CUCV.
Same here, in Michigan...my truck looks great. I also never wash it all winter. Car washes around here just rinse your car with recycled salt water.
I wash it at home in the spring, and wax it in the fall.
@@michiganman845Yes, also do not take it to car wash as the pressure wash will take off the coating. -A fellow Michigander who fluidfilms and does not wash all winter
@@michiganman845 Yeah, the recycled salt water is the worst thing for your vehicle.
I've wanted to drive my 1986 CUCV the last couple Winters but have not (since its never been undercoated). My plan is to use this undercoating process this coming Spring so I can drive my Blazer through the Winter.
Can u apply it in cold weather?
Good video--would have been nice to see a control as well. A third, untreated metal plate, just to see how badly it would rust under the same conditions/time without any product on it at all.
pretty safe to say a raw, untreated plate would be covered in rust. i don't think anyone would be blown away by this result.
Yeah I should have thrown one under there just to see. I originally thought that it would take away form the comparison so I didn't make the 3rd plate.
@@adamcoe No one wants to get blown away. The third plate would be a nice visual and a good motivator.
@adamcoe I know it sounds like water wet on the surface but it's worth seeing if the conditions for trust where met.
I personally went with Surface Shield because I pressure wash the undercarriage. FF washes off easier. Can't go wrong with either one though
Thank you for taking the time to test these. Very helpful.
Awesome video. Thanks for taking the time to put it together.
I had my 2022 Cadillac coated with fluid film black for underneath and clear for under the hood and all doors. I went back to the installer 1 year later to do a recoat if needed and I was shocked on how well the fluid film was still applied AND there is absolutely no rust anywhere! So glad we went with this product for I see it protecting my car for years to come.
That because you live in Arizona 😂. Trust the experts Surface shield is much better!!
This is the kind of testing we need thank you!
I waited ... and couldn't wait for this!!!! I was so excited you released it. Saw the original video by you and was impressed... even more impressed you took the time to do a long term test AND FOLLOWED THROUGH!!! Thanks...
I appreciate that! I'm glad you enjoyed it!
Excellent video just did both my truck using the blaster surface shield in the gallon containers.
All these lanolin products are the best antirust solution out there. I have used fluid film for over 15 years now and zero rust in PA.
It’s good stuff but man the lanolin smell is something you gotta get used too.
Hahaha I've learned to like the smell. Took a few years to get to that point though lol
Don't care what people "say" online, I apply it myself in my shop, I do everything at cost so I'm sticking to what has been proven and cheap, fluid film all the way!
Good comparison, can't go wrong with either. Been using FF for about 15 years. Zero complaints.
This is how tests should be done. Wonderful and informative video. Thank you!
I'm not paying 2 1/2 times the price for something that needs redone every two years. Fluid film will only require annual touch-up and costs around $45 a gallon. The critical inner surfaces will not erode. Surface shield is only a small percentage lanolin so lanolin-based is misleading at best. It is petroleum based with enough lanolin to impart a slight odor. Great video.
Appreciate that! Yeah, I didn't see a big enough difference to justify the cost. Fluid Film has been doing excellent on my jeep up to this point
Used Hydraulic and transmission fluid the best by far lol
@@mikethorntonr1is this a 50/50 mix?
I liked using wool wax this year, but next time I need to apply it when it's warmer out. Thick stuff
Looked up the SDS for Woolwax composition & ingredient information Lanolin 60-100%
I sprayed 2 vehicles this year in 50 degree weather next time I'll do it on a 80+ degree day
Doesn't drip off curious how well it'll do this winter, we have plenty of salt & sand here paid $70 per gallon little more expensive than Fluid film but people say woolwax smells better
Great test BTW!
Amazing results. Anyone who lives in the rust belt needs to see this.
Very cool test. Thanks for doing it.
Insanely good video. Thanks for making it.
Thanks for doing this!!!
Both are great products and each can have an advantage depending on application.
Wow. Thank you for your video!
Excellent comparison! The nice thing about both products not being petroleum based is that they will not degrade rubber or plastic. Thanks for the vid! -Glen
You'd think that. As a Fluid Filmer I can 100% say overtime (3 to 5 years) it softens rubber, softens plastic and will make your door seals sag. All of those are better than rust imo
This has been my experience. All the rubber under the Jeep looks like the day I bought it!
You probably didn't get much fluid film on those parts. I used the fluid film spray gun and five gallon buckets of the stuff on my fleet of plow trucks while they were on my lift before winter for years and the damage to rubber parts was easy to find later when the trucks were back on the lift again for maintenance or repairs. Learned to be careful and avoid spraying soft material as much as possible. @@BustedBeaters
I dare you to look at the SDS for Fluidfilm 😂 main ingredient is "Refined petroleum oil, hydrotreated heavy paraffinic"
Great video. Good dedication
Thanks for the in-depth video. I'm looking at getting a new Chevy Express van and this is definitely something I'm going to be spraying all over the underneath. Along with inside the door panels. Also removing any tape that actually traps the water inside the door panels as well.
No problem! You'll be glad you put in the work now a few years from now!
Great video .. well done !!
Good to know! Thanks! ! ! 👍👍
Id love to see a test with panels that are rusted and seeing if either is better at slowing the corrosion process
same here!
Fluid film will stop rust so long as you can seal all avenues of oxygen.
I would also be very interested in this. I don't think it will stop the rust but I imagine it will slow it down some.
@@BustedBeaters It appeared to fully stop the rust when I sprayed a rusted section on my Accord some years ago. As I continued to check it the corrosion never got worse.
plenty on youtube testing these products
Wonderful video!!! I was on the fence wanting to try one of the Big 3 (Woolwax, Fluid Film, Surface Shield). I don't live in an area where it's as necessary as up north, but I do have older vehicles and would like to preserve the metal on it. You sold me on Fluid Film, which I was thinking about trying anyway simply because it comes with the graphite premixed giving it a very nice black finish on the underneath of the vehicle! Thanks for making this!
Thanks! Appreciate it! I don't think you can go wrong with any of them. I think FF is a good balance of price and performance. I also like having the option of being able to remove it if needed. You'll be happy with Fluid Film for sure!
I always rely on fluid film. Way to cheap and easy to use not to. I use maybe 3-4 aerosol cans a year, 30 bucks, and an hour of my time. Coats everything under the Tacoma and it hasn’t rusted, and what little rust was there when I bought the truck hasn’t spread or gotten worse. Definitely works. I love the fact that every year when I get under to spray everything still has that waxy feel and it’s still on there.
Damn we get ripped off in canada. $20 a can here, gallon $115
In Norway. 140 kr per spray can. ( 10, 40 $ )
Do you wash the old stuff off or just apply another coat ontop
@@jasonsmith4243 I usually run it through a car wash with underspray or pressure wash underneath. Let it dry a day then coat it.
I started using Fluid Film when they sent me a free can to test on my race jet ski. That was probably 10 years ago. If it can work on a saltwater jet ski, it can work anywhere.
Fluid film doesn’t dry and that’s what I like, because it will “heal” any place it gets rubbed off because it spreads the longer it sits…I also watched a video where a guy tested every oil out there on a plate and left the plate outside for 6 months, pretty much all the competition disappeared except fluid film, which spread and grew 3x the size, and (what sold me) was on the backside of the steel the fluid film was coming through…THAT is the game changer!
what about lithium grease? i guess that would work also if you don't mind the dirt sticking up
😂You are right about that. It is extremely sutiable for cold climate because it will solitified when cold. I recall I travel to Montanna in summer and the fuild film I applied the previous fall start to melt. That is the moment I becomes a fuild film fanboy.
I apply fluid film in the spring and late fall just before winter after enough time goes by I think it actually penetrates into the steel. My mechanics love working on my rust free vehicles and the bolts come right off without a fight
Thanks! Good review. I have been using fluid film for several years and am happy with it. Using the spray kit I am able to spray above the wheel wells on the inner bed and the front fenders!
Yeah the wands are so nice to have. Let's you get it into so many tight areas!
I treated the underside of my teardrop trailer and so far, it's working perfectly.
Great update. I used Fluid Film on my JK last year, and I’m doing my new to me truck with Surface Shield this year. Only reason for the switch is that the Surface Shield was on sale and $30 cheaper for 6 cans than the Fluid Film.
I don't think you'll be disappointed! I was pretty impressed with both of these products
Wow! I never saw SS for less than 150% the price of FF. You got an AMAZING deal!
Thank you for that video!
This is all I needed to see.
Now thats dedication! Great video
Thanks!
My 2017 ford super duty parked outside in Illinois winters with plenty of salt. Zero rust. Before this aluminum truck i had a steel body raptor i used fluid film on the frame and krown rust proofing in doors cab corners rockers etc never have an issue with rust.
This is consistent with my results with fluid film. I'm going into my third winter on the original treatment, and there's still a nice film on the frame and it still looks good. I've done spot touch ups to the front of the frame a couple times since then, since that takes the brunt of wear, but I have to imagine that inside the frame still has a nice coating considering the outside of the frame still looks so good.
😂I used to fluid film. And I get the shop to apply it every year just for the heck of it. And it just keep building up over years. By the time I need to pull my transmission. The coat on the chassis is thick enough to become a layer of its own. Too bad, the shop I went to stop doing coating 3 years ago.
Note on the Surface Shield aerosols, I bought a 6-pack from Amazon in September and applied 2 of them today, neither gave me much trouble even though they seemed to have the same cap everyone complained about. I kept the cans warm (~70F) until just before use and shook them often during the application process, both of which may have helped.
When the cans were almost empty they only sprayed well when held upright, but that seems like normal aerosol stuff. Maybe I was just lucky, we'll see what happens if I end up using the other cans.
I got 8 cans to do my tow truck and none of them game me and issue. I made sure they were warm (room temperature) and shook the hell out of them before use. No issues here. Will definitely keep using!
Yeah, I had the same experience. I was able to empty 5 cans to the point there was not a detectable amount in the cans at all. I kept them in the Garage, which was about 50-55 degrees or so.
Great video! Got a gal. of SS to spray under my '92 jeep YJ, I plan to also apply it inside the frame... Will see how it works. Hopefully the wet cover will still let me see any oil leaks in the event they may appear...:) Thanks for posting!
Oil leaks will be harder to spot but, you'll notice any sort of oil on the ground. Those frames are known for rusting. You'll be happy to have it coated!
@@BustedBeaters Indeed. The frame on my YJ surprisingly is in excellent shape for its age and the reason I want to coat it . I can add some UV die in the engine oil and use a black light to check for leaks periodically though so oil leaks would not be big issue. Where can I find the hose adapters to spray inside the frame? Thanks again!
Good video.
I have 5 work trucks, 2 trailers and a skid steer in NH and MA all sprayed with chainsaw oil (from a fluid film gun). Ages 1995, 1997, 2003, 2006, 2007, 2010, 2013, 2015.
Sprayed every year or every other year.
No rust on anything bought new, VERY LITTLE rust on anything bought used.
I use the fluid film and surface shield rattle cans for touch up and for skid steer implements.
Very pleased with products.
But unfortunately i have run into the spray problem with surface shield recently- probably 8-10 full cans that dont work.
Good video, thanks again!!!
Ppreciate it!There's been a lot of people who have mentioned chain saw oil. It's pretty thick stuff so I imagine it does work well. The SS cans seem to be hit and miss for a lot of people
Do you guys wash out the inside of pick truck box wheel wells every year or just spray more FF or SS in there on a yearly basis ? I do wash certain areas of the truck and reapply the protectant yearly . Other areas I just reapply without washing .
Great video. I know it's too late but it would have been interesting to have seen a control.
Yes. I debated throwing a control plate in. I was concerned that the control would take away from the comparison. Looking back, it would have been nice to have.
Great job with the video.
Thank you!
Theories and opinions are fun to discuss, but data and science is how we make important economic decisions.
Another outstanding episode.
great job. would have been interesting to have a control sample, a 3rd piece with nothing on it.
Next time!
Thank you so much for doing this! I've been convinced that Surface Shield was the superior product, but was discouraged by those aerosol reviews. I don't have access to an air compressor, so aerosol is the only way I could do it. I'll be picking up some Fluid Film!
They're both pretty amazing products! You'll be happy with Fluid Film!
great content
Thanks for the awesome video! I just finished fluid filming my truck here in Michigan. I have a question as a first time user, do you spray off your trucks underbody throughout the winter or just leave it all there throughout? I’m concerned spraying it off with high pressure will take off the fluid film some too. Thanks again!
I under coat heavy before winter and don’t do any sort of under carriage washing until spring (New Hampshire)
I also spray in the fall and do not touch the underside until spring. Just spray it and forget it! It'll do it's job!
I use the wand on final rinse setting for undercarriage. It uses same pressure as a hose. Will rinse it off but won’t really take any fluid film off. Try washing this stuff off an exposed panel it’s really difficult to unless you have soap so no soap on undercarriage til spring
Good video, would have been great to have a 3rd piece ie the control with nothing on it for comparison
Looking back, I do wish I created a control piece. I was afraid it would take away from the comparison, but I think it would have added to the video.
Great test. I’ve also heard Cosmoline is less tacky and picks up less dirt and debris.
"Ten year of using cold galvanizing compound". My tread read toward end and decide if is for you.
I used to use Fluid film, but in the summertime heat, it breaks down and starts to drip everywhere. Now I use WoolWax. It is harder to apply, but MUCH thicker than either FF and Surface shield. I bought the Wool wax gun and use my air compressor. It's been over three years since I first applied it and it is still very thick.
Fluid Film claims to be lanolin, but according to the SDS it's 50-90% "Refined petroleum oil, hydrotreated heavy paraffinic"
Whereas Woolwax is 90%+ lanolin, the only listed chemical ingredient on the SDS is "Sulfonic acids, petroleum, sodium salts" 5-10%
@@thebigmacdinteresting, but how come the SDS doesnt mention toxicity. If it is petrolium product. It has to be bad for human. And Ive been told the food industry uses the fuild film as well.
@@user-jh6vt8vx4v mineral oil is the base stock for non-synthetic motor oil, but is also the base stock for baby oil. Vaseline is also a refined petroleum product. Both are considered safe for humans.
the surface shield cans must of been updated. I got mine months ago and had no issues.
thanks for reaction
I bought a 6pack of surface shield in cans and only used 2 so far and didn't have any problem with clogging. the first can was not used all at once either and worked just fine.
I hope the rest of your cans behave the same way!
Good video. Would of liked to see a third plate no protection
Yeah I agree! I really should have added a control plate!
Everyone knows it would be rusted to hell. No surprises.
I liked that the Surface Shield was not easy to remove! BIG question I have is how was the vehicle cared for in the Winter. Did it get washed in an automatic car wash? How often? Was there an undercarriage wash included with the car wash? It'd be nice if you could answer these questions for all of us to see. Thank you.
The Jeep did not see any car washes over the winter. I washed the body a couple of times but never sprayed the undercarriage. Once the Fluid Film is applied, I don't touch the bottom of the Jeep until spring.
I would have added a control plate that had no treatment at all but this was a great experiment. Thanks
Yeah I should have added one! Next time!
On my second year of fluid film runnin from Maine to Mass coasts, salt everywhere. Still looks great.
I think a product that picks up less dirt is a big plus. I have been doing undercoating for years and a problem I see is with cars that drive on dirt and gravel roads end up building up a lot of sand around the wheelwell areas. Most people do not bother to do any pressure washing and leads to a thick build up that holds moisture.
Yeah, I agree with this. I've seen several cars from Florida that have never been in snow a day in their lives. They rust out where the sand collects in the wheel wells like you said. The sand just holds that moisture against the metal.
Those are both impressive to me as someone that doesn't really have to worry about rust turning a vehicle into nothing but surface ruse is still a thing which neither of those seem to have basically any but i guess that all only works where its applied so if you miss something and are not looking at it often it can still be a problem
Yes this is very true. There's a lot of areas I'm sure I miss. The goal is to coat as much of it as you can though!
I think the spraying issue with Surface shield is due to how thick the product is. If the can gets too cold or just sits in the garage it doesn't spray well or at all, but if you warm the can it returns to spraying as normal. (I left mine in front of a mini Space heater while i was working on my car) once the internal contents were warmed up the can returned to spraying as normal with zero issues. Hope this helps someone.
That's good to know. I haven't had a problem with any of the cans but I imagine that warming them up would help a ton.
spot on it is the temperature
Great point. Just don't go crazy with the heat of course! I did mine in the fall when it was probably about 60-70F and had no issues.
in Australia everyone argues about whats better out of Inox mx3 and Inox Mx4, would be great to see a comparison like this for that
Two more undercoating products I've heard of. I had no idea there were so many of them out there!
I like that i can remove FF w/ solvent like alcohol easily in order to service a component w/o making a mess.
Plus 90 years vs 2 years on market is a factor
I like knowing I can take it off easily as well. I wouldn't want all the dirt and grime to be difficult to remove down the road
Good test. Generally in an experiment you want to include a control though.
Yeah I'll have to add one foe the next one!
I've been using fluid film for about 5 years (bought a gallon can and spray it on with an undercoating gun yearly). Working great so far, only rust I've seen is in spots I missed. Looks like surface shield is around $20 more for a gallon can than fluid film.
Have you tried OSFO to convert ferric oxide to ferric phosphate BEFORE applying these products? I'll bet that would work very well on existing rust.
I have not. I don't see how this would hurt anything so it's worth giving a try!
I haven't tried fluid foam, but surface shield worked great in the winter, but the first hot/sunny day in southern Utah it just basically melted right off truck onto driveway. Oh well, I guess it is for winter and cooler areas only.
Yeah it's mostly used in the winter. Weirs that it just melted right off the truck though. I have had a couple people say the same thing happen to them when using Fluid Film
great video. way to stick to the long game. If you do this again, add a 3rd plate as a control. We dont have rust so bad around my way.
Appreciate that! I should have added a control plate!
I did watch the video, You probably already said the answer to my question, Did you spray those two pieces of metal one time, In the two years,, I probably should have just asked , How many times did you spray those 2 pieces in the 2 year test?, Thank you very much, Bobby Miller Detroit.
I just sprayed them once at the beginning of the two year experiment. Other than that I didn't touch or clean them throughout the 2 years.
I have surface shield but will buy FF next time if it’s cheaper as I can’t see a difference between the 2. Plus I like the fact you can remove FF easier if needed. I like to power wash off the old before putting a new coat on. Surface shield is harder to remove once hardened.
Yeah. That's the biggest thing keeping me feom switching to SS. I really like the fact that I can remove the product if I have to do any major repairs or take the car to a shop.
You don’t need to power wash off the previous years coating . A light hose off with water and apply new product right on the thoroughly dried surfaces.
I’ve used FF for years but am going to switch to SS because it’s harder to remove .
I sprayed fluid film black on my 2012 silverado last year before fall. And here in northern michigan winter the back half of my frome had all washed off not even half way into snow season. Very disappointed. Think next I will try woolwax.
Yeah I imagine in Michigan you're dealing with pretty rough conditions all the time. Woolwax, Surface Shield or even one of the more wax based products may work out better for you.
I go through car wash with underbody spray every week until they stop salting the roads. Costs me like 11 bucks each time, $44/mo, usually 2-3 months of winter but only 1-3 months of snow, so $132 per year at the most from car washes throughout winter and my frame is still metal solid
Yeah, I haven't had much luck with this. I know someone that did this exact same thing and their truck is shot. The car washes around here recycle the water they use so you would essentially be pressure washing salt water into your undercarriage. But hey, if you have a good car wash and it's working for you, I wouldn't change a thing!
If you spray with FF or SS you don’t need to spend any money on underside washes.
would have been interesting to have a control w/o any protection applied.
Yeah I agree! I really should have added a control plate!
@@BustedBeaters Year 3 review, we expect to see it in there! Just etch in the date you slapped it on there lol
Which one resists the pressure washer better? I’ve been using Fluid Film but I’ve noticed it does come off in the car wash
Surface shield will handle the pressure washer better. There's pros and cons to this for sure. Although it will be much harder to remove with the pressure washer, it will be equally as hard to remove if you have any repairs that are needed.
The nozzle clog is pretty easy to fix, a quick blow from the compressor and it's clear. Obviously not as ideal as a nozzle that doesn't clog but it shouldn't deter from using Surface Shield.
Interesting. I did not have any nozzles clog on me but this is good to know!
I wonder if warming the can up a little would help
@@TheRealChappy I was just thinking the same thing yesterday as my nozzle repeatedly clogged. It was -2 C out. I'd bet heating it some wouldn't hurt.
@@amp_mechanic woolwax needs to be warmed before spraying, maybe it would help
Gotta do a video on krown t40 or krown KL73 it’s the same stuff as T40 just marketed different
I have received a lot of comments on this. Going to have to give it a try!
I like that Fluid Film offers Black, which looks better on truck frames.
I also purchased a can of surface shield, and the nozzle clogged.
Yeah the black does look very good! The surface shield cans really seem to be hit or miss. Seems like some people have no issues and others run into the clogging like you did.
I have a 2014 F150 raptor, I plan on using the fluid film on it. There’s no rust coming through anywhere that I see when I spray this product in there will it neutralize anything that might be starting?
It won't completely stop the rust. Unfortunately no product will do that but, it will slow it down substantially
From what i see you can't go wrong with both.
Especially when im at the beach surf fishing.
Exactly how I see it!
Amzoil M&P is my favorite so far
from my experience.. you have to shake the can for surface shield very well for it to not clog up. I usually shake it for a good minute or more before spraying.
Good to know! I didn't have any cans clog me. I must have shook them pretty good lol
I feel a lot better that I "cheaped out" on a $55 gallon of Fluid Film instead of the $86 gallon of Surface Shield. My two vehicles are already pretty badly rusted and I didn't have the time or ability to properly prep all the surfaces. After seeing this, though, I have hope that I can extend the life of the vehicles until an engine problem sends them to the salvage yard.
They're both great products in my book! Can't go wrong with either of them. I'm sure you'll be able to extend the life of them!
Think I’m gonna go with fluid film just because it picked up less debris and it cleans easier. Just got a 2016 Tacoma and I want to keep that thing protected. Thanks for the video :)
I think you'll be happy with it!
Next time use plastic cable ties to affix the plates. You can induce galvanic corrosion with a dissimilar metal such as those magnets.
For sure! I was expecting more corrosion around the magnets due to this but really didn't see it.
Fluid film does state " not sticky" may explain the pine needles? Fluid film is available in black, makes my trucks frame look great, don't know if Surface Shield is available in black?
A lot of people seem to be really happy with the black stuff. I don't believe SS comes in black. I know that Repair Geek has a video on how to turn it black if you were dead set on SS though!
Would you put silicone coating under a lawn mower deck?
I have heard of people putting Fluid Film on decks. Now sure about silicone though
Excellent. Would have been a better test if you had a control, a bare metal plate, also.
Next time there will be a control!
I have been using Boeshield T9 for a few years. Wouldn't trade it for either of those products.
There's a ton of great products out there!
Use an air compressor to blow air into the surface shield cans as they start to gum up and not spray well. The added pressure helps get it out. Not perfect but it helps
I assume you take the nozzle off and put the air in the stem. How are getting the air in there/ what mechanism or attachment are you using?
Good to know! Hopefully they will figure out a way to keep this from happening in the first place.
@@gy5386 yes I take the nozzle off and use a rubber ended blow tip air gun and cover with a rag (just in case any blows out) and quickly push down on the spray can tip at the same time I push the compressor gun air into it for a couple seconds. You can feel the can pressurize more then put the tip back on and resume spraying. I’ll re-pressurize the can a couple times as it depletes. I do the same thing on any product in a can that has lost pressure but still has product. Surface shield absolutely sucks coming out of a can but I do what I can to get all out of it that I can. They really should figure out a way to make their spray cans work better!
@@BustedBeaters yeah surface shield really should figure a way to get the product out of the can more reliably. It varies can to can but most of them suck so I use the air pressure to do the best I can to get it all out. I’ll be applying more for this winter soon and like I said it’s not a solution but it helps. What’s funny is fluid film cans spray much more reliably but surface shield works longer so far but it can be quite frustrating to get the product on. #getyourshittogetherSurfaceShield
Great video btw! Commented 3 weeks ago. Came back for an update. Surface shield sucks in the cans. I had 6+ cans of it and not one of them would spray more than 5 seconds. I threw them all away. Trash. The fluid film cans spray perfectly. Amazon sells 5 gallon buckets of both and the Fluid Film is under $200 and Surface Shield is $275.
This is about the same experience I've had. Except for the SS cans clogging. I have nit had any clog but I haven't really used that many either! Thanks for stopping back in for the update!
don't know about Surface Shield but Fluid Film is what is known as a thixotropic fluid. Thixotropy is a time-dependent shear thinning property. Certain gels or fluids that are thick or viscous under static conditions will flow over time when shaken, agitated, shear-stressed, or otherwise. So a rattle can just picked up and sprayed will soon fail in the spray part. Plus it won't creep as well as it should. Shake the beans out of it however and do so throughout and you will be fine. Probably same for Surface Sheila.
Interesting. Learned something new today. Thanks!
It looks like FF may creep a little more. At 40% of the cost, I'm staying with Fluid film. Also the Fluid Film cans work. Also I would rather work with a lanolin based product rather than petroleum. Both are good products.
I've had a good experience with FF but I don't think you'll go wrong with either.
don't think there isn't petroleum as well in both of these. read the Safety Data Sheet, you won't even see lanolin listed on the ingredients. also this from FF "FLUID FILM® is formulated from specially processed wool-wax, highly refined petroleum oils and selected agents to provide corrosion control, penetration, metal wetting and water displacement."
Lol. They both are petroleum based
I emptied an entire can of surface shield under my car with no hiccups. That was a only a few months ago, so maybe they've improved the nozzles after the first edition?
It's possible! I hope they did improve it.
I bought 6 cans of the surface shield before I knew about clogging issues. Anyone have any tips to make them useful??
I have heard of people warming them up slightly and spraying them upside-down to clear the clog. Hopefully you can get them working again
I have met the originating chemist who formulated Fluid Film and I Agree with your conclusions. However, being on the inside track, hearing the Formulation Story first hand from the chemist who originated the original formulation, I will stick with the Fluid Film. Do you recommend an annual touch--up of both / either / neither ?
Now there are 30 Plus Fluid Film selection formula numbers, beyond clear, or Black. if bought from the actual distributor inventory.
I reapply every year. Just in my experience I would say that a maximum of 2 years. By this point both of these products have mostly dried out
I’ve tried a number of things under my car, including FF, and all wash off quickly within a few trips on the saltways here in Maine. I’m baffled by the claims that this stuff works.
I find it hard to believe that it has all ben removed, especially if you're spraying in the frames and doors. Those areas shouldn't be getting any sort of water spray. You do live in Maine though so your winters are much harsher than the ones I go through.
Here in finland, some people (me included) use chainsaw oil mixed with wax based protector. I daily drive an 31 year old car and they use too much salt here :D any oil works really, but some hold a little better.
Yeah I know exactly what you mean about the excessive use of the salt! Good to hear the chainsaw oil is working out for you. I've been amazed at how many different products people use to undercoat their vehicles with.
@@BustedBeaters So am i. My father used to brush some tar mixed with oil on his volvo back in the 70s hah. We have one of the oldest car base here in finland cause people have always done what ever they can to keep motoring. Old cars are appreciated here a lot.
Than was my recipe for years , bar oil heated up on the wood stove in my shop I’d melt some wax toilet rings into it and spray it on hot . Now I use FF but will try out SS because it adheres better .
I can verify the surface shield cans clogging I had two half full cans I threw away even after trying to unclog them
Can you spray this on a frame that is already rusted?
You can. It'll slow down the rust for sure
