I try repairing cracks on an exhaust manifold with JB Weld Extreme Heat.
Update: July 29, 2017
I recently gave this car away I no longer own it.
My contact information: welkingvue@yahoo.com
Hey everyone thanks for your comments and giving feedback. I no longer have this car I gave it away many years ago.
😮 I would have gladly bought it that blue is awesome
Protect this man at all cost, the world needs more like him... Peace and love to all ✌️
good review.. I'm not sure why everyone is judging this man so hard. thanks I saved money because of this video.
The reason they are beating him up because of there millennals
Dan Green no it isnt lmao
Dude u can’t gunk it on you need to work it in there
Not judging him, he's just not doing it right and that's why it didn't work.
I took (cast iron) manifold of, made the crack bigger in a V shape, drilled hole at the end of crack so it stops cracking, ultra cleaned the crack and pushed the JB in there and it works.
@@duncandonovan5270 nice man, that actually sounds like it might hold up. how long has it been working for ya? i just replaced the entire manifold at about $160.... which is expensive
"I use this cotter pin to mix it"
After 2 sec:
"It's probably better not to use a cotter pin"
😆
Great video dude ✌
Thanks for the honest full review for those of us trying to learn to do stuff ourselves. Nicely done.
He seems very kind. I liked this video and I was curious about the jb weld high heat epoxy 😊
I would definitely buy tickets for your stand up comedy show, if you had one!! You're a natural!
0:44 the sound of the electronic zoom on his handheld device was stimulating lol
i like nesquik the strawberry one
So racist, #chocolate milk matters!
If you tape a vacuum on the end of your exhaust and turn it on while applying the filler, it will help pull the filler into the crack deeper for a better seal
I've used JB weld for years. I've successively used JB weld to repair leaking fuel tanks and cracked oil pans. JB weld is good stuff. However, it's all about preparation. Use carb cleaner or acetone, paint thinner, or gasoline to clean your work surface. Sand and sand some more to rough up the surface so the JB weld will attach and stay attached. After you have cleaned the surface with some cleaner, ie: gas, carb cleaner, acetone, paint thinner, or whatever, then clean it again. Point being is to make sure the surface is super clean. Grinding a v-groove at the crack is a good idea, but not always necessary. When applying the JB weld, make sure you're penetrating the crack really well. It's not going to hurt anything to get some down inside the exhaust manifold. And always, always apply the JB weld to the WHOLE crack, from end to end. None of the crack should still be visible when you are done applying it.
Thanks for sharing the information.
I wonder if driving a taper pin into it first would be good thing also?? I couldn't find header yet for mine so go some BlueMagic QuickSteel ThermoSteel from ebay. Will try when warms up more outside. Has 2400"F on package so??
That was helpful as fuck to me.
Also as some have mentioned down here you seen some type of mesh along with the JB weld would probably help particularly in this situation
Ty
I need some jb weld, I'm cracking up 🤣🤣😂🤯😊
@@djanebybarbie2267 u need some JB weld to keep those fluids in
You haven't given anyone false hope for providing an honest review, it might work on pinholes and tiny cracks but for a full crack right through like yours I think you would need a tonne of it which would probably cost more than a new manifold
A new manifold is the only dependable solution . Thanks for taking the time , to demonstrate , it's no good . People appreciate your unique personality,, you're awesome , dont change .
When you judge somebody , someone else is judging you .
Thanks for watching!
Define dependable. JB weld works excellent in a lot of situations and can hold up for years. And is obviously way way cheaper. Just resorting to the replacement is kind of dumb unless you have unlimited funds then go for it. This is like mechanic saying oh you need to replace rotors every time you do your brake pads it's the only safe option. But actually in reality, no.
@d-rockanomaly9243 I don't know in what universe jb weld works on cracked manifolds but I would stay there because it seems like a where anything is possible. Comparing turning your rotors to putting jb weld on your cracked manifold is silly . Go to the junkyard and get a used manifold but throwing money away on jbweld is throwing monet away and not getting a sensible solution I'm not rich but I'm not stupid .s a valve job and manifold is more expensive than a manifold . Durrrr. Thats when being poor cost even more money not doing the right repairs when you discover them can cost you even more money. Don't drive it catch a ride until you can fix it you always have a choice . That said I ve tried it all and I to would use jb weld to survive the moment it don't mean it's good or recommended sorry you are poor
Video: "It didn't really work"
Commenters: "Thanks, I can't wait to try it myself!"
Some experts recommend getting the crack a little bit wider and shoving the JB Weld down inside through the crack which the directions indicate
Thank you for this tip
If you read the instructions, it tells you to open the crack/hole to almost 1/8 so it can penetrate and seal. Otherwise, this was quite painful to watch. I have to say, the cleanliness and organization of his garage is impressive....
If your welding then yes but, this stuff isn't a guaranteed fix and if you do drill it out it could cause more problems if it doesn't hold up. If it doesn't hold up you'll have a bigger leak. Exhaust repairs can be a pain.
Open the crack to penetrate. = )
My man, just put jb weld on the crack😄! You are the cutest squeeky guy on TH-cam! You need to have a channel on TH-cam where someone follows you around all day! I would watch this!
He is one groovy guy. Paper brush. Why not? Well I think we learned why. Comic value = priceless.
I ordered this product and am still waiting for it to arrive. In the mean time I had some regular JB quick weld on hand, so I used that on an exhaust pipe leak between my drivers and passenger seat. 700 miles later I crawled under the car with a bottle of windex and sprayed the repair area, while I had a hose hooked to the exhaust of my shop vac to pressurize the exhaust system. No leaks like before. Amazing JB quick weld held up on an exhaust pipe, since it is only rated for 450 degrees. I'm sure an exhaust manifold gets much hotter than the exhaust pipe though.
Yea I’ve measured mine with a heat gun after driving at 718*F before. Mind you it’s a stainless steel turbo manifold, but no boost was applied so even then it was hot as hell
You tried it but no good. Contact the company to get a refund on their crappy product. Your video was good and let people know about this product. Thank you Welking for taking the time to make video.
This guy is truly awesome
Thanks Welking - Thanks for taking the time. This is how we learn. More importantly, this is how we learn to decipher the thousands of 'products' we have out there. Was thinking about this sorta fix (in a quest to save $$$) - but i suppose because of your experience, ill take a different route. Peace out Brother.
Thanks for watching.
Soooo. My 1st name is Micah and middle name is Jarad... If your last name is Vinson, you are my long lost twin.....
@@mjv8507 nice. my first is Micah and middle is actually Jared. Last name isnt Vinson, but one of my bf names is??? either way - YO MY BRO!!! (how many micah J's can their really be) I thought I was the only one but I welcome ya.
Great video bro, don’t listen to anybody making fun. Good review.
Thanks Harvey!
well, its official. i have now seen everything on youtube.
I love the way he is never not moving
I hear some kind of noise like predator is there next to you
Hot car. Love the boost gauge without the boost.
😂😂😂
it's a tacho gauge, he doesn't have a tacho on the oem cluster
Might have worked better with a few layers of fine wire mesh like a bug screen.
Apply with an acid brush.
Thanks for giving us all a little chuckle !! 😁
“Apply an acid brush” u my friend are a godsend! Of course it seems obvious now, thanks!
Oh, and fine wire mesh! Yes! The acid wash I’d NEVER heard of.
Yeah my muffler on my motorcycle was leaking around both ends, i used one container of this, i applied it in small layers letting it cure before applying the next layer. Then i let everything cure for over 24hrs. Holding up great so far. The instructions also say to really push the jb weld into the cracks and build up several layers. You may have done that but it didnt look like it
You probably applied it better than I did.
This jb weld works better if you grind the crack about 1/8" & then 1 coat of jb weld
1/16" thin, and before it dry
Add 1 or 2 small pcs of
steel screen to reinforce the crack, [ the screen you r going to use, its the same all the windows screen have]
after it drys add 1 more coat of jb weld,
But I recomend to weld it or replace the part
He didn't use it properly
You can keep adding and adding coats of JB weld and still going to break even with the metal screen, heat from engine creates expansion and contraction because the type of joint, you can see that also the thred-olet is cracked.... so the best fix is to weld it using a welding machine.
I love real videos with real results. Great job
Thanks for watching.
Thank you sir for a good honest review of what could happen using this product. Keep well, regards from Ireland ☘️👍
Thank You!
I used a q-tip to mix and apply. Worked pretty good.
Thank you for the video. I had the exact same results. Got to replace the manifold at the end.
This needs to go viral.
I can appreciate the extra salsa dance steps on the side, great moves
Directions say enlarge crack to 1/8 inch. You didnt read the directions! O2 sensor install could crack it again too!
No it don’t work on my 22re headers exhaust, but now I must figure how to get it off the header exhaust nuts and bolts that I covered. I created more work on my disassembly. I putting new exhaust on if can get the JB weld off.
I was half expecting an origami brush when he pulled out the paper.
This is exactly what I was looking for, thank you
💀💀💀💀💀
I wonder if it would work better if you followed the instructions for larger holes. They advise buttering a piece of fiberglass matt and laying it buttered-side down over the hole, and then buttering the upper side. The fiberglass would reinforce the paste.
I had to give this a "thumbs up", just because lololololol...
Seriously though, would love if this dude was my neighbor!
Lol. Step by step instructions probably better than I can do. I will give it a try in a sec and give my personal review.
It's so hard to find good comedy today. I'm literally crying. I hope you will produce more videos like this. Nice job.
Thanks for watching!
@@WelkingVue have you tried using heat tape with the JB compound? It will prevent from cracking
Didn't try that. I don't have this car no more.
Well, it was worth a shot before spending a bunch of money. Thanks for the video!
Nice video! You know you could have paused it at any time while filming to use the restroom. Lol
Same thing happened to my XJ manifold. Used JB Weld and about the same time period is what it took the JB Weld to FALL off of mine lol
Ended up just changing it out
Did this nigga just say he drove 220000 miles since the crack happened
Slamd Yati yes
😳I thought the same thing!,😂
It was around 219,000 when he repaired it and 220,000 after driving, so he put around 1,000 miles on the repair.
Headers / exhaust manifolds had the most extreme heat and pressure. Selling it is a case by case situation. Same person can do it and have it work on one car and not another. No guarantees. I would try sanding the loose rust off and leaving it where it looks a little discolored and not so smooth. Sometimes this works a little better as these type of sealers get better grip on the pores . I do this on the mufflers and down stream cats. As they are a little cooler. Usually works good unless its a large repair. Sanding to the point of shiney metal doesn't give you a great grip as people may think. A body guy wouldn't prime over shiney metal. It needs to be dull. You can try to dull it with a very fine sandpaper. 600 grit and up. But, if its a crack then you really need to try and force it into the crack first, then when it cures a layer over the area and perhaps another layer but, spread over past the area previously done. That way it is trying to wrap around the area a little. Much like gripping with your hand over an area as to putting your finger over it. Nothing really will fix these types of cracks like welding. But, its worth a shot
I tried jb weld and it doesn’t work,,, I ended going to a muffler shop and have the manifold welded. It passed smog. My Honda has 353000 and still going strong ,,,, happy miles ahead!!!!!!!
If I ever have to deal with this again I probably do that too. Wasted time trying find the part at junk yard.
I would not let this man drive a car
Just stupid ass comments
Good job man showing what you did right and what you did wrong.
Thanks again for the video
Thanks for watching!
This was weird as hell but Cool I guess lol. Dude was hella funny, glad he showed us jb weld extreme heat dont work. Just subscribed
I am very happy you just saved me on the job I was going to use the jb weld thank you very much jb weld is junk something to use if you are a thief and just want to make a quick sale selling your junk, that’s all JB Weld is worth thank you very much for the info. Excellent video.
Its re-cracking because of the vibration of the two broken pieces ....try the JB weld putty that can be applied as a more thicker application to keep both sides firm
Need to drill small hole at the end of the crack to stop it from growing, relieves the stress poin
Sometimes you have to try anyway. You never know, it might just work. It was good experience and now you have a little more knowledge on what to do with a grinder and a drill for prep work by some of the constructive comments before you add the JB Weld if you ever run into this again. Original crack was too far gone. When stuff like this cracks it's probably a known issue by that point and worth buying the new manifold because problem was probably corrected. A good example is the Chevy Trailblazer and Envoy manifold. The new ones allow for some flexibility.
You are right. I wanted to try and see if it work.
This guy needs his own TV show on NBC.
Duplicated this on a cracked manifold. On mine, it cracked during cooldown after a long drive. Fortunately that long drive resulted in an emissions pass😁. Seems like the material becomes elastic upon heating, resulting in a bubbling up. It probably thins out resulting in cracking when the temp changes. For me it worked in a pinch to stay on the road, but count on a new manifold shortly after.
Too much pressure in that part of the manifold plus the engine mountings are probably shot so its flexing. Good vid. Thanks!
The crack may have deeper into the metal of the manifold. You only applied the JB to the outside of the manifold. The JB was a temporary fix. Manifold replacement would be a permanent fix. In California, you will not pass a smog with an exhaust leak.
Thanks for the video!
Jb weld is a very good product. However the vibration from the motor may have contributed to the cracking of the repaired area. Try the exaust header wrap thats used on motorcycle pipe s that should really help out. Good vid thx for sharing.
Thanks for watching!
I had my first repair on my 2002 Civic on the exhaust manifold look like this. Then I applied another coat and it appears to be holding. Time will tell, but I'm not holding my breath. If it doesn't work, it just needs welded
That sucks. Thanks for the warning.
I think QuikSteel High Temperature would work better.
Welking Vue ive tried the quick steel on the same crack, and it didnt hold up, but it did say to clean the crack and bevel it first and i didnt do that. chip off the old stuff and try to sand into the crack a little to give the putty a good surface to grip and maybe try to let some quicksteel stay out and harden slightly so its thicker, and press it into the crack first so that it doesnt seep through when you put on the second coat. ill try the same and see if i can make a video. thanks!
Thanks for the information.
You have to sand it until you see the metal! If you still seeing black red orange brow or any other color that is not the metal color (shining gray/silver) its doomed to fail from the start! Also do a proper weld don't use JB weld.
www.gofundme.com/helpingvue
Regarding what some commentators say about cleaning the surfaces all the way to silver metal color I'm asking how come that the putty didn't flake or came off anywhere ? Obviously it adhered well which means the preparation he did was good enough.
Now let's talk about the 2nd crack. Was it on top of the original one or in a different location? If the latter, it means adhesion of the putty to metal is fine but is lacking strength to hold itself. Obviously the manifold suffered a dilation and the putty could NOT resist it.
Lesson? Expand the original crack to 3-4 times wider, of course make sure all traces of dust are gone, fill the new opening with a glass-fiber piece of fabric and put some putty on the fabric before you force it into the crack. Now smear the area with the putty but in 2-3 hands each as thin as possible waiting to cure before each application. I can guarantee you it will hold all the way to 300 thousand miles.
Awesome thinking and ideas.
@@WelkingVue JB does say to make sure the crack is 1/8th of an inch
Thanks for sharing this with us.
Run the car to heat the manafold up then Disconect the battery. Arc weld a stainless steel welding rod into it. Peen it out a bit then hook up the battery and heat it up again.
You maybe able to tack weld it into position on the car but to do a proper job will require removal and definitely pre heat before welding.
The JB weld is most likely intended to get you home or to repair shop temporary fix. The bigger question is why did it crack?.
I don’t think head is what cracked the job weld because it don’t come off or anything it’s made for head not the pressure of vibration or whatever caused it to crack so in my case I think it might work
I like your accent, makes you sound very kind😊
I think that it would be better to use a furnace cement to seal hot places even before the catalytic converter and the exhaust pipe lines.
Looking at this crack I think it's a tough one because the oxy sensor will force the crack to widen because it is across tge sensor port. If anything would save this manifold I would think it needs to be stick welded with a good penetrating weld and then it might have a better chance of holding
I've had success with jb weld around the manifold of my Mitsubishi Lancer Had an air leak due to blown gasket I didn't want to have to replace the gasket as I really don't have the time anymore to spend time on repairing what I done was applied a fine amount around the headers to the block and let it set for 10 hours, 8 months later it's still bonding great no cracks at all, I think it's best to apply this stuff fine, no applying in big chunks just apply it over the crack and wipe away the excess whilst pushing into the crack
That sucks I spent 7 years in the NAVY on submarines and we used JB weld sometime but in the end it cracked like yours . but it did get us long enough to fix it right. I agree you should try sometime else . I did find out that if you grind away the old stuff but with a small wheel not to damage it further . Do not get one of the ones on a drill that cause more damage. I also would save up money to replace it. But be careful removes it can open a big can of worms I would like to know what you did next. Keep up the great videos.
I just gonna pass the car on to someone else and let them know the problem they can decide if they want it or not. I had this car for many years already, it's time to get a new car. The miles is high I don't feel it's worth fixing. The car is still good and if I let it go, at least let it go in a good way by not giving someone a junk car, but a decent car.
ncrdisabled Submarine vet JB Weld on a submarine???!!!! WOW!!
Looks like the people I wanted to give the car to didn't want it. I gonna either continue repairing or sell it or put it as planned non operation.
How much are you asking for it? Maybe I know someone who would buy it. Depending where you are at. I still have a lot of NAVY friends all over the world.
Yep just for quick repair but never leave it on . It also is not very often in my 7 years I used it maybe 6 times
When he showed the cotter pins he used I burst out laughing, lol
Dey R car-pens,lol!
Thanks for your video, and your honesty,you have help me save money! Iam going to try Muffler weld!
lol these videos keep getting better. thanks man.. lolol
Good video I’m going to do that to my manifold right now. Thanks.
I just used regular JB weld to put the handle on my new grill, poorly made, couldn't get both screws in at once (Char Broil table top) hole alignment was off, so I bought the JB weld and the next size smaller screws, put JB in the hole sockets, coated the screws, then coated all the exterior parts for a solid fit, I doubt if I'll get over 300F, see if it holds...
He drove 220.000 miles in 4 weeks folks! 😁
Thats a record for sure. Lol
Ive used this stuff on a exhaust manifold leak. It leaks where it mates on the block... makes a ticking noise. And well i had it on for like 4 years and it finally broke apart and starting leaking again... i just out more on tonight.. if this saves me 600+ for a shop to fix it then why not.
I work on my own cars.. but 32 year old manifold bolts... no thanks.. id rathee use puddy lol
Somebody give this guy a Oscar
That repair is called a band aid....but you did try and made a vid. Prep is key in repairs.
Thank you for proof of this product.
Where do I find this product in South Africa JHB
The job pays 20 hrs weld at the dealership 6000. Good deal 30$fix better then new, runs lot quieter now even fixed the 🧵 threads
l broke a Suzuki diesel manifold, welded it with arc stick, 15 year later, still hold. JB weld is not for structure repair, it will not hold up a structure crack. Also my 5 " wise busted, l stick welded it, still good in many years later.....
thanks for showing this video on how the typical crack of a 90s Honda Civic cannot really be repaired but hopefully it will be enough so you can pass inspection. just remove the shield on my 98 Honda Civic with 170000 miles original catalytic converter with California emissions. I have the same crack in the front of the O2 sensor and also the back that goes all the way down to the cat. I just need enough of the crack to be blocked so at higher RPMs air doesn't get sucked in to the manifold triggering the O2 sensor and running rich. check engine light catalytic converter efficiency code both O2 sensors fairly new. I reinforce the area with a washer on top of the J-B Weld along with some wire Twisted in a Criss-Cross pattern.. letting it dry now we'll see how it is on Sunday..
You'll probably know what the real deal is after driving for a few days or weeks. Good luck on that.
what happened? did it hold?
Thank you for saving me money 💪🙏 keep it up. Thank you.
Without cleansing surfaces down to bare native metal and compensating for expansion, that job was guaranteed to fail quickly.
Exactly, you can't apply something to dirty metal and expect it to work. Almost all instructions tells you to use it on " clean or cleaned " metal in order for it to stick to it. Putting it on just the outside surface is about as effective as using a band aid.. and not removing the manifold and allowing for heat expansion as well as cooling is a big mistake.
It did stick on good. The problem was the JB Weld cracked.
I think the real problem is as you said before the design. As I said in one of my comments, I had an old dodge with a similar style exhaust manifold. I bought a replacement and was told by the service tech to be sure to torque the manifold in the correct mount bolt sequence to avoid cracking again. And to be sure and use new gaskets. If not done in the correct sequence it puts stress on the middle of the manifold and eventually it will split again. Other vehicles that had the same problems were the old Chevy Love pick ups, they were plagued with split manifolds, the reason was you had an aluminum head with a cast iron exhaust manifold, problem aluminum and iron react to heat differently.
Anyway I hope you got your car fixed. :o)
Red Woods grind a "V" into the crack. and work that shit into the crack.. and maybe you would have a chance. . you messed up. . not the products fault. .
www.gofundme.com/helpingvue
I like this guy regardless
I had an old 1990 Dodge van that had a cracked exhaust manifold, split down the middle like you have. Best thing to do is spend the money and buy a new one.
About the JB Weld Extreme Hear putty. I would have pulled the manifold and clean the actual crack surfaces first. Don't forget there has been carbon from the exhaust blowing through the crack leaving impurities on the surface of the crack. Just applying the putty on the outside of the two split pieces is like putting wood glue on the surface of two pieces of dirty wood, it won't hold.
I don't know how good or bad JB Weld is but I had a buddy that bought an old service station hydraulic lift for cars. It was used and had a dent in the lift piston. To make a long story short, he used JB Weld to fill in the dent and then filed and sanded it then installed the lift in his garage floor and it worked perfect for many years.
Thanks for sharing.
Love this guy!! Subscribing myself!! Much Love!!
Ok i jist put jb weld on the egsost manifold it smoked off completly befor i pulled out of my parking spot it was for the 750 degree not sure if i should even try 1000 degrees or not
The reason it cracked again so soon is because expansion contraction..... Mix fibers into the jb... 8 would use carbon fiber because it's used to make exhausts and when used with high temp epoxies is awesome..... Of course I would take off the manifold and braze it myself..... People that don't have those skills or tools can take it off and to welding shop and get er done for twice the cost of the jb weld.... And if course the replacement from a wrecking yard or a new part is the best way and not really that expensive..... Over the years I found is better and cheaper in the long run to properly repair things.... An exhaust leak will fry your valves quickly and that will cause warped heads and many other problems.... And when you pay the tow bill it will cost twice the price of the used part.... Then the engine damages could cost easily 10 to 20 times the cost.... What I would have done if doing jb weld would have been grind out the rust to clean metal drill small shallow holes part way thru... Might even drill few clear thru o the both edges of crack then stitch it up with wire mix jb weld with carbon fiber then lay on a layer then place a piece of aluminum can or better sheet metal with holes drilled thru to help the bond then lay another layer of jb over that allow to set well meaning couple days.
. Now that will not crack cuz of the carbon fibers.... Might even mix some wood stove door seal rope in the first layer with carbon....
JB Weld HighHeat Epoxy Stick 8291 might have worked. The Extremeheat 37901 is a non-psi rated filler & adhesive, not a bonding agent like the HighHeat stick rating is 600 PSI at 400ºF (if area properly prepped, and/grind metal and clean w/ non res. solvent) I haven't used the filler from JB Weld but the Thermosteel from Blue magic, if (and again) the area is properly prepped.. ( I use an angle grinder and brown disc till the metal is shining and then wipe or spray 91% alcohol on the area to clean and have not ever had a single issue with any of the big brands) But I can say the thermosteel I repaired a burner tube using all 3oz of it in a 150k BTU furnace, and have had no issues and that's under a clean and blue flame.. But there's no high pressure exerting force on it.. Think the water col is = to just 4 psi and thats spread out thru the rest of the tube.. Have not used the JB Weld filler, but the high heat metal epoxy on properly prepped area whcih this was still too dirty in this vid, works perfect and i think it would have worked there. HOWEVER.. That spot, Ive fixed 2 manifolds in that same spot in 2021 with a cheapass harbor freight stick welder on the lowest setting.. And while it looks like spatlter city, That crack is dead and the fix forever.. as is all the fkn splatter around the bead (the bead looks nice) Maybe I shoulda got a Millermatic 250 with a 30a spool gun with stimulus instead of 2 8balls, 2 hookers and a striper named Sue I kept as a live in housekeeper and toy for my old lady... Yeah.. About as real as the Miller Welder that's not in the shop.. Well.. the hookers and stripper arent real. Can't promise nobody went skiing.
"They're not made for mixing anything..."
no shit, lol
yeah the best one is quicksteel extreme heat the stick. not the orange tub
Use Furnace cement which can get off line or at most hardware stores that carry Furnace parts
going to try that out.
tried and no luck.. i did do it in winter times though. but gave er 3-4 days to cure and no luck.
Good attempt, but I think a new exhaust manifold is in order.
It didn’t work for me either it just cracked after I drove it I just ordered a replacement and I have to replace the o2 sensors now one is burnt due to being right next to the manifold
Great informative video. Thank you.
Probably should've went light, and added more layers after curing a bit. Layer after layer
