You won't find anything better
Used it to repair a 10 inch crack in the haul of a boat under the water line. This stuff worked great with woven fiberglass sheet. Takes a few layers to get fiberglass to correct thickness but this epoxy cures like steel. Highly recommend.

Repaired the garage doors so I didn’t have to purchase a new set of doors
Worked great. I used it to repair my garage door. Then paint it over it with the original paint color I had on the door. Can’t even tell it was repaired. Save me getting two new garage doors.

Good resin
I haven't known jb weld to make a bad product. And this is no different. Most I can say is it did the job like it should, didn't cost as much as some other products out there, and it arrived on time.

Strong Stuff!
I used this to repair a crack in a sprayer tank. I trust JB Weld products because they hold when nothing else will. I just wish it wasn't so expensive, but you get what you pay for, and if you're in a jam this will get it done. My tank sprayer will end up in a dump some day but I'm sure it won't be because the repair didn't hold.This shouldn't need to be said but WEAR GLOVES!
