Anyone else using this stuff? It's awesome!
I use this stuff on everything, all my vehicles, all my friends and family's vehicles, four wheelers, mowers, door hinges. I love it. I mix in a little clean 15w40 engine oil into the fluid film for vehicle undercoating. It works great!
I use corrosion free 3000.. Canadian product
Use fluid film for working on everything. Do the larger undercoat job with Surface Shield it lasts longer and does not slump as much
Yeah surface shield is a better product, better than fluid film!
My Ram gets a blast of this every year....I did my big drill press sitting in an open quonset this year
It works so well! I use it on my mill, lathe, drill press, and even lawn mower for the winter too...not just for vehicles.
Nice job! I use the black version, because it's easier to see where I have sprayed... plus it covers over the rust better for a little while. I usually spray as late into the season as possible, so it doesn't get washed off with rain... So what I do is make a double boiler out of an old pot and hotplate from the dollar store... I put the gallon in the pot with water... I check every 10 minutes or so and stir until the wool wax reaches 100F. I can then pour without slapping the funnel and it goes on so quickly.
Nice tips. I haven't seen the black version up here yet in stores, whereas most carry the original. Other than the slow pour, the spraying even when cold with this sprayer has worked well...but I have heard warming it up can make it spray even better.
Just don’t want to wait too long, once the salt is down, you start sealing it in, I know a couple places around where I live stop doing it as soon as the first salting is done.
Can u spray then on car coil over to prevent rust?
The bubbling from the aerosol cans is the propellant boiling off. I'm pretty sure. I'm not a rocket scientist but I did stay at a holiday inn express. I'm in Canada and on rennlist as well. I'm using corrosion free for my rust proofing but may switch to fluid film when my corrosion free runs out. To mask the smell of FF, I bought a glade plug in air freshener refill which is basically scented oil and mixed it into the product. Now it smells like apple cinnamon
That's awesome, apple cinnamon rust proofing :)
that is impressive! my 2018 silverado has more rust than i would have thought possible in 5 years! I will be using this goo asap!
Unfortunately it doesn't reverse any rusting that has happened...but in terms of protecting what's there, it is awesome stuff!
The set-up minus compressor is about what a shop would charge, I'd imagine. I'm definitely going to get set-up with this, as I like older vehicles and road treatments seem to get more and more corrosive each year.
Yup, a gallon is usually $50-75 or so, sprayer is $50-100. A single gallon can do 2-3 vehicles first time depending on size. So after the first year, you're really looking at $20/year to rust proof a vehicle. Well worth it!
I have the same gun but use rust check. Also in Canada and it’s worked great for my vehicles over the years. You should pull the plugs in rockers and spray in there as well. Also the inner fender panels, bottoms of the doors etc.
Yup, I have done more than what's shown in the video, definitely want to get into every little cavity you can, great tip for those reading this!
I even remove the front and rear bumper covers headlight and tail lights. I agree, Canadian winters suck.
05:39 100% correct If you want it done right, do it yourself. Because of time constraints, I've paid nearly $500 to have 2 vehicles initially coated with FF and none were done as thorough as I would have expected for that price. I still applied more to missed areas when I got the cars home. Good video! I use Fluid film Woolwax, NHOU, and PB SS as well as Amsoil MP HD. All do a really good job, WW for wheel wells is def. better. But any initial coat I like FF since it creeps so well.
Agreed! I'm a big proponent of DIY, you can take your time and do things right.
Can it be sprayed over rust or should it be used on new vehicle's only?
of course brand new vehicle is always better but it will work on whatever condition. applying anything is better than doing nothing! it will at least slow down the rust
Thanks for the video.
welcome, hope it was helpful! :)
I've heard Wool Wax which is similar - also lanolin based doesn't smell as bad. And I think they claim it's a bit thicker and stays on better. Hard to get though, online only I think. I got to try it out.
Yup, Fluid Film is wool wax lanolin base, so ya, same idea...just probably different mixes of exact ingredients.
Love me a good Fluid Film video 😁
Hell ya brother, we all do!
woah, just realized what channel you are...thanks for stopping in and watching :)
The bubbling when using spray cans comes from the liquid propellant gas that the fluid film is mixed with. in the can. It evaporates and creates bubbles when it gets out into normal atmospheric pressure.
That makes sense :) thanks for adding that!
use a drill and paint stiring attachment and it will pour easily, you can't mix it good enough with a stick , also ya can leave the cans in hot water for 30 min before and it will spray much better
Good tip...it doesn't separate too much, but a drill stir would definitely do a better job!
Start by taking off all of the plastic inner wheel wells and door plugs and clean the underside very well. I use Surface Shield myself.
Good tips...especially for the first application!
TY!
Welcome :)
How would you recommend washing the undercoating after applying the fluid film? I'm in Michigan, and I'm buying a new 2023 car. I want to protect it with fluid film, but should I not use a pressure washer to wash the undercarriage after applying it? If I should wash it, I read that people said it'd take it off... and if it does take it off, should I re apply it every 6 months.. every year? If you can help, I'd really appreciate your opinion and time.
Yes, it will wear off with pressure washing, not all at once but eventually will. Frankly I don't bother washing under the vehicles in winter, it's just driving more moisture into places IMO. I apply fluid film once yearly in the fall.
I just finished my truck using cans
Hopefully it holds (Canada)
And yeah it does smell
How many cans did it take?
I don't mind the smell :)
Hey Dude, thanks for the vid. It was very helpful. @9:51, you were talking about 'access holes'. How do we know if a certain hole is an access hole and not a hole that is not supposed to be sprayed into?
OR
Can we just spray into every hole we can find and we will be safe?
Ty 4 the reply!
Almost anything in the frame/body is okay. If it looks like steel inside, go for it.
Just avoid exhaust, heat shields, and anything that passes through to interior.
Spraying into every hole you can find is always risky, god only knows how many illegitimate children you’ll have out there.
For the smell, I read someone say that they mixed a Glade air freshener in the Fluid Film before application, and it left their vehicle smelling like apple cinnamon. I'm not sure if that's true though, and I wonder if you could mix a small bottle or two of essential oils if you wanted to do something similar (and it might help thin the Fluid Film a bit for application).
Entirely possible...the smell doesn't bother me but for someone who doesn't like it those might be worth a shot and I can't see the harm in it either!
the single most important aspect of this video is...... have a hoist. doing this stuff without a hoist is brutal and borderline impossible to do it well. if you don't have a hoist kicking around your garage, i don't know what to tell you, but good luck.
6 ton jack stands (enough height but still stable) and a creeper...it's how I used to work on vehicles before I had a lift, not as pleasant but totally workable.
Thanks for the great vid. Do I need to put a primer/paint pre or post coating with Fluid Film?
Nope, it's just a rust protection coating for pre-finished metal surfaces...on vehicles the frame and such should have been coated originally
@@SomeGuysGarage Thank you!
Rustiest thing is the oil plug! I also spray the dust plate for the rotors being careful not to get the caliper and rotor.
Those pesky splash shields rust out no matter what you do, just like exhaust, all the heat cycling.
@@SomeGuysGarage Damn it! Just give me this one that will work!
Do you wash off the salt and grime from the undercarriage of your car during winter, or do you just leave it be knowing it's covered with the product?
It's best applied to relatively clean undercarriage. Mostly want to get any serious build up off, since it will never actually get down to the metal to protect it...but you also don't have to be completely spotless. It can be damp when applied (not dripping wet) so keep that in mind too.
@@SomeGuysGarage Thanks.. But I was not asking about application, I was asking if you wash the undercarriage of your vehicle during winter AFTER the product is already applied to it..
@@can-cruiser Oh sorry, I misunderstood. No, I've never washed the undercarriage of the vehicle during the winter (or ever really lol I only wash the top side maybe once or twice in the winter).
Would you suggest removing existing rust before doing this procedure?
Light surface rust? Probably not.
Flaking/heavy rust? Yes, but the vehicle likely needs more work at that point than a coat of rust proofing.
I have the lemmer rp100 gun. I think its the same.
My quick connector to the wands started leaking on the 2nd year of use.
Anyone else have issues witn the quick connect?
Not here...there should be an o-ring in there somewhere though, check it's seated properly and not torn.
Hey thanks for the vid. I just bought the same gun. My question is how do you clean it....or do we need to?
Welcome
I don't clean the gun out, just leave it with whatevers left but making sure it's standing up when stored...I do blow the spray wands out though (just with a normal air blow gun).
Excellente many thanks
@@jeanmarcblanchet7393welcome, if you have any other questions, happy to help :)
I have the same gun, it won't spay surface shield at 80psi am i missing something? It came with no instructions. Did i just get a dud gun?
I do run it higher than recommended pressure...do so at your own risk...but I spray unthinned cold fluid film with no issues this way.
What pressure do you spray at?
Depends on the gun, though I find a little bump up from this ones recommended pressure helps.
FluidFilm is safe for any kind of suspension parts. only soft door seals are not safe. the squishy stuff.
I haven't had any issues with bushings or rubber parts swelling, but I don't actively try to spray them. The big thing is it won't hurt paint or other materials and won't drip, it's quite a good product.
Where did you buy the spray gun ? Thank you
Napa up here in Canada...you can get it on amazon.ca but not .com it's an underbody spray gun.
Here's a link: amzn.to/3RQnl8r
Stuff works great but has gone way up in price unfortunately. $16CAD/can now 😢
Or even $18...but wait for sales, can go down to $10-12. Watch princess auto and peavey mart and canadian tire
$10 a can on Amazon
I use POR415. One and done.
I've heard good things about the POR products too, haven't tried them myself though.
@@SomeGuysGarage I have been using it for years and have had no dramas. Your method and product work no doubt though
@@rickchowsr2532 right on, will have to check it out one of these days :) Thanks!
Por 15 works great been using it for 25 years, clean important, use in a gun with a tad of reducer and spray pre treatment Ammonia they sell to turn rust to neg ION if rusty, use to be cheap but not anymore. Price And don,t forget your Body Flush HAHA
NEVER?
Ok, practically speaking, you can't coat every single square inch of your vehicle in it...so yes, something is bound to rust eventually.
However, realistically speaking, if you keep up with coating, the stuff coated will outlive the useful life of the vehicle.
Cans of fluid film are now $18.99 at canadian tie. Sucha a large jump in a short time. Welcome too greedflation.
You can still sometimes find them for $10-12 at princess auto or peavey mart on sale.
Just checked, peavey mart has them on for $13 right now...that's something at least
@@SomeGuysGarage It seems they read your comment. They jacked the price to 18.99$, to match CT.
@@amunkhufu yeah, probably supplier pricing is up...they do still go on sale for less though.
Used engine oil only way to go
No way...drippy mess that doesn't stay on.
Though is cheap lol
Lots of tests on TH-cam. Used motor oil is terrible at preventing rust. Fluid Film consistent comes out on top of compounds that stay tacky. The only thing that might be better is Cosmoline that essentially dries and is more durable. Cosmoline needs much more prep and is more expensive though.
@@peterscott2662 agreed! Fluid Film is easy to get, easy to apply, and safe to work with too...as a DIY product it's awesome, but there are a few other good options out there too...like the guy who mentioned the POR products.
@ProjectFarm has also done some great comparison testing!
Nope
Why
@@kenj.8897
Can I ask you which woke province you are living? Because in my province of socialist Ontario the corrupt government put a lot of salt on the roads. I am curious if fluid film better than Krown rustproof.
I assure you we get a salt bath here all winter long...fluid film does an amazing job keeping it at bay.
