Using JB Weld to Fix Rust Holes?

[@joe-hp4nk]

I have never owned a welder and can't weld. You're videos without welding are much appreciated, thanks.

[@LakesideAutobody]

I'll continue to provide them as they are just as good as welding in my opinion - there's no worries of water or moisture getting past the seam :)

[@DallasLawnGuy]

I have two welders but sometimes there are situations where I want to do something like this and not use a welder. I'm also just a hobbyist.

[@kingdomcalled1403]

Back in the early 70’s a guy brought me a motorcycle race bike where its piston was fractured. A piece of the piston skirt became lodged between the crank and the lower case fracturing the case. So I went and J B Welded the case, bored out the cylinder so I could put a new piston in it, and then filed down the case halves, tapped out the locations where the case fastener bolts once were and the guy raced the bike that weekend. It was a lot of work but, I couldn’t get a new case for at least two weeks so… if you’ve ever watched the movie “On Any Sunday” with Steve McQueen… you know us hard core motorcycle racers of that era were back on the track every weekend no matter what came our way that tried to stop us 🤪 in other words; we were a bit nuts, if you will. I’m going on 76 years old and still doing things things with J B Weld that might shock some people. Not the quick or fast cure version… just the long cure type. I haven’t had the same success with the fast cure. Back to the J B Weld fix… to the best of my knowledge, it worked fine. Well… I never saw him again ? Every time I mix a batch… I think of that early 70’s motorcycle repair, lol…

[@anthonycosentinomusic5054]

@@LakesideAutobody Seemed okay. It was a few dime and quarter sized holes by the rear lights on an old Dakota. I actually used the JB Weld metal putty - the 2 part you mix in your hand. I applied it from behind and over the hole and squeezed the two globs together. They hardened up, I sanded, primed and hit it with a spray bomb. I wasn't looking for a professional job, just to get rid of the holes. I WOULD be interested in seeing if the regular JB functions the same as a panel adhesive (seems much less expensive to me).

Repaired a hole in the side of the case on an 8 horsepower Tecumseh snowblower engine. Previous owner had run it out of oil and it snapped the rod and put it through the side of the case. Cleaned up the pieces of the case and repaired from inside and outside with J-B Weld. After a new connecting rod and some muriatic acid to clean the gold aluminum off the crank journal, the engine runs great years later

[@pauldow1648]

Used JB Weld to rebuild rusted lower windshield pinchweld area. Front windshield rubber dryed and failed over time allowing water to reach pinchweld and cause rust. 1966 Chevy C10. Replaced windshield and gasket and molded JB weld in contour of pinchweld so rubber gasket sealed. Beauty. .... Plan on trying to use it to repair and build up rusted portion of wiper motor mount hole also.

[@davidhucks9216]

I used JB Weld once to patch a hole in a gas tank, was actually a crack a little more than an inch. First dried the tank. Drilled a small hole at either end of crack to prevent further cracking. Sanded lightly and applied generous amount of JB Was lasting years later when I sold the car. Great stuff.

[@LakesideAutobody]

Nice idea with the holes at the end. The stuff does work on a lot of things for sure - good story :)

[@opinionsvary]

In my opinion: The end holes move the crack across a radius, but it still needs to be stabilized. JB Weld would need a solid patch to cover beyond & a round the perimeter pressed close to the crack taking advantage of the hydro static stick. All by itself JB Weld would crumble. Holds up well in gasoline environments making it worthy of any tool box. Realistically, JB Weld is best suited for restoring gasket surfaces corroded from electrolysis such as a thermostat housing or water pump. You could use silicone instead, but with JB, it degrades to a powder when smacked or abraded making it ideal considering what typically clogs radiators & heater cores.

[@chrisgraham2904]

I've used J B Weld, other epoxy adhesives and polyurethane construction adhesives for various auto body work. Adhesives join the components together and seal them from moisture and corrosion. Low stress panels don't always need to be welded. You'd be surprised how many body components on new vehicles are bonded with adhesives, rather than being welded.

I have a truck with rust holes in the cab floor from a leak from my loose windshield. I'd love to put in a proper welded patch but just don't have the proper tools. It's between something like JB Weld and taking it to a body guy and paying fair but still very high price to have it done right. Probably $300-400 vs $10. The floor is still sound so I'm thinking that JB Weld would do the job. We all know that perfect is better but perfect just isn't possible sometimes. I have lots of toys that need things and one has to set priorities.

[@daxinventor3542]

I agree that JB Weld is probably the best repair substance that I have ever use. Second to none. The only problem that I would have with repairing rust on automobile's could get really costly. JB Weld is not cheap. Bondo type materials are much less costly per square inch of surface's. Maybe JB Weld will see your video and create something that is less expensive to compete with Bondo.

Thanks for the video! I used JB Weld and some 20ga sheet metal on a Swiss cheese fender. After removing the rust and DA sanding the inside of the fender I formed the sheet metal to fit closely.

[@podamis314]

I was thinking that it would be good to squeeze in more JB weld to fill the narrow space between the inner and outer sheet metal. To reduce the amount of water that can be trapped in that space. Also it seems to me that welding always has a disadvantage in that it cooks off the factory protective coating on the inner surface of the metal and you can't recoat it once the repair plate is in place.

[@LakesideAutobody]

Sad thing is, there is no protective coating in the pinch welds from the factory. Some companies use weld through primer and others treat the panel after the welding process leaving two pieces or three pieces pinched together and welded with nothing to protect - thus the rust at the edge of panels usually. Best way to protect is after the repair. kzbin.info/www/bejne/bonEi3WvbKx2baM or kzbin.info/www/bejne/r2GYlYGuqZKhjMU

Nice. Thanks for your comments

[@vinco2livecom]

JB weld and fiber glassing make great temporary / affordable patches and do help to preserve the remaining sheet metal. However, Tig / Mig welds might be a better repair option since jb weld and other epoxies have different expansion and shrinkage ratios than the surrounding metal and /or the patch in heat / sun or extreme cold. Over time this could cause pitting/bubbling, high / low spots, unevenness, or imperfections/warpage in the finish/paint. Depending on the condition, make / model, and value of the vehicle full metal repairs might be a better option.

Be sure to get a good brand. Used one from a local car-oriented chain and it was horrible. Sometimes it turned rust black and sometimes it didn't work at all. I am currently using Corroseal which seams to work well. Just not sure if there are any issues with applying body filler over it since I don't believe the rust converter should be sanded post-application.

[@kirbyroad5743]

@@Marcoosianism I always use corraseal before I patch. It's the best chance of killing that rust before you close up that area. I use fiberglass poly like duraglass over it so water won't swell it up like regular bondo. And only use bondo and glazing filler over that. The secret is to seal the inside so it doesn't come back through. I also spray bed liner on the inside or backside of patch. It's buttoned up and solid and most important waterproof. It'll last years.

Jb weld is extremely expensive and other than the price-is great for small areas. But short strand fiberglass will adhere even better to raw metal. And will never separate crack or break off.

Nice Video! I agree that JB Weld is a good option for rust repair. I have used it as well as Loctite PL Premium 3X contruction adhesive. No hardener needed. Dries like a rock! Cures in a few hours, but best to leave it overnight. It's sandable but you need some elbow grease to do it. Good to make a foundation using the 3X and some metal. Then use bondo over it.

Thanks so much for the tips and ideas - have a good week :)

Absolutely perfect brother..

Thanks my friend - glad you liked it.

I used JB weld to repair a 4"x2" chunk that broke off on my Yamaha aluminum outboard lower cowl. It worked great!

[@quackquack6116]

Looks good to me great option aside from welding

[@spurgear4]

I used to run a strip of masking tape along the body line and sand to it. Worked pretty good.

I use the 5 minute jb

I JB Welded a shifter on an automatic transmission itself with the cable and it's lasted many, many years. Had to make it work when I threw a new one in and it was broken. It's still working...

[@delpsdayoff3372]

Im just learning body work myself.. ive recently discovered jb weld is a fantastic filler for rust holes. The only advice id give here... it bothered me when you sanded the jb weld and went right to bondo. No dust clean up done? Was it edited out? Also you spred the bondo well past the repair area up past the body line.. it was cringe worthy. (For me) and a 3rd note... instead of using heavy filler to go over the jb weld.. just use more jb weld. It sands beautifully. If its left with a tiny air bubble or to use more jb! Body filler is antiquated. Jb doesnt wear or shrink or crack. There actually teaching to use jb in autobody classes now.

[@LakesideAutobody]

Body filler is easier to sand than JB + way cheaper, thus the coating of Bondo. Can't be afraid to spread the filler larger than you need - aids in getting the repair straight. Finally, you're right it is a good idea to blow the dust away before the next coat of anything - filler, primer, etc. Happy Holidays

[@justafanmarvel9669]

Are they selling jb weld in something larger then little tubes to bring the cost down? Otherwise people will stick with the body filler to cut expenses

[@LakesideAutobody]

@@justafanmarvel9669 It is expensive - might want to explore the use of panel adhesive (also expensive) - I once glued the whole floor of a van in with metal roof cement/caulk 'cause I didn't want to mess up the galvanized coating by welding it in. I glued and screwed it. It never moved again - that'll be the last thing left on that van 50 years from now :)

[@justafanmarvel9669]

@@LakesideAutobody ok I will probably use a combo of your suggestions. Thanks

[@rob12449]

I got this idea today and wanted to see if it has been done. Glad I found your video with excellent demonstration. I was welding in a patch panel and burned a few holes and was thinking, I hate the thought of trying to weld up those holes and know there is enough good weld to hold it all together. I know ordinary body filler wont cut it because it is not water proof, and thought maybe jb weld. Now will try it for sure.

Why not just weld a patch in does a better job in less time

[@sdaafasfad]

I personally don't have the skills to weld sheet metal nor the tools so if I was trying this kind of job at home, it'd be easier to use a putty based substance like JB Weld. However I can imagine that if the rust damage was more extensive - it wouldn't be as easy and would likely require a professional to weld it.

[@LakesideAutobody]

[@bulldog8934]

@@sdaafasfad for that type of rust, welding isn’t really an option. You’d have to cut down to viable metal first rather than just grinding away the rust.

[@kylegable1273]

Everybody don't own a welder bro,sometimes u gotta work with your budget

[@hotrodhendrix1]

Used it on hard to reach areas and tiny holes. Any real rust areas will still need to be replaced but this is nice for specific jobs.

[@tousshong9438]

Looks great and nice job finishing out the rust spot

[@phantomroller]

Nice video, well done. I have used J B similarly and had mixed results. Sometimes a permanent repair resulted ( more than a couple years) other times the rust re appeared in short order ( less than 6 months). In all cases the metal had been sandblasted back to "pure white metal" , no visible sign or rust. My suspicion is that there was corrosion hiding either on back sides inaccessible opr in seems and that it spred back from there, but dont really " know that" . Still, for a quicks repair where you dont want to cut the whole section away and weld in new metal, J B is my first choice.

[@LakesideAutobody]

I have found that if the panel can drain and be able to dry out on the inside it lasts quite long. If it can be undercoated on the back side - even better :)

[@darlenegeorgeboyd8493]

I've been using JB Weld for filling trim and emblem holes for many years. If possable use the epoxy to glue some metal screen to the back side of the panel. When that dries use the epoxy to fill the hole and push it through the screen. The screen helps keep everything in place.

I'm not sure but here is a JB welded cab corner after 5 - kzbin.info/www/bejne/n5XVfa2pr5eYgsk (drivers side)

[@drfumesta2212]

I use JB weld all the time. This old truck I'm working on has had 3 different types of rear view mirrors screwed into it over the years. For these small holes in the door, I put a piece of masking tape over the hole and then smear JB weld from the inside. After it cures you pull the tape off and it's basically flush with the surface already.

[@LakesideAutobody]

I once jb welded a metal egr tube that came right out of the pipes behind the exhaust manifold - hotter than heck right there. It lasted forever. Sold it 10 years later and it still was sealed.

[@08logcabin]

Works great, I used JB weld to secure strips of sheetmetal to fix holes in the roof line and windshield surface. its been 18 months of WI weather and its holding up just fine.Al

[@jerrydesilva7359]

My 66 chevelle was patched using marine-tex , way back in 1975. Bought a big can to repair a boat, and a motorcycle transmission side case, had lots leftover, that became the ultimate metal patch. If you don't need alot of it, panel bond , and JB weld is just as good .

[@LakesideAutobody]

I'll have to look into that. Thanks for the insight - have a good weekend and Easter :)

[@boydmerriman]

Good idea. I think I did use it one time for a small hole, but didn't think of it as a broader solution.

[@LakesideAutobody]

[@jacquelinechellis4036]

I think it solves the problem of moisture penetrating body filler from behind. Also helps where metal is too thin for good welding results. More working time as well not as messy as fiberglass resin patches. I will try it maybe for some small areas on a floor board where it will seal well. Prep is everything good prep job on that. Thanks for video and idea.

[@LakesideAutobody]

You're welcome - try to make sure your panel can drain and dry out inside - that really helps :)

[@Fred82ndAbn]

I have some slightly pitted sheet metal in the trunk of my project car that does not merit replacing the entire section. I have removed all the rust as much as possible without removing any more metal and treated the pitting with phosphoric acid to neutralize what's left. I plan to use JBweld to cover the pitting instead of body filler as it will add rigidity to the panel and will make for a better repair IMHO. JBweld is more water proof than bondo for sure. Time will tell if it holds up which I expect it will. Great tip!

[@LakesideAutobody]

Thanks - I'm sure it will be just fine. Let me know how your project goes :)

[@danherring5676]

I just did the same a couple weeks ago on a rocker panel patch. It worked great.

[@magnang]

I have done this with JB Kwik. Sets in 5 minutes. It isn't quite as strong as JB Weld, but seems like the time saved is a good tradeoff. Obviously this is on non-structural areas
