An excellent product to seal a crack or a seam depending on the material you are trying to fix.
I had a crack developing in the outside lip of my hot tub. Not a large crack but I felt It would get worse over time. I spent a lot of time trying to research fixes and products. This company makes many epoxy type sealers and glues to repair just about everything and when finished it is pretty water resistant depending on the type of repair. This J-B Seam Weld in white color did the job. It was easy to apply to the seam and filled the seam nicely. It hardened quickly and can be sanded if you so please. Just remember epoxy products need to be mixed thoroughly and evenly to work well.

Great for seams, not for strength
Great for seams, not for strength. I should have bought a different product that was strong
User
plan on at least 48 hr for it till fully cure
I needed a white jb weld for a project, but they dont make that....and with the 10,000 different confusing JB products out there now this is the closest I could find. It sets up quick, so quick that the included mixing syringe was unusable in a matter of minutes. (such a waste) 24 hours after letting it dry, it still seemed a bit soft, 48 hours later its finally getting to where I think it should be. so DO NOT use this if you plan on putting any type of stress on it for at least 48 hours. PS this is also in 70+ degree non humid weather. I havent sanded yet, so i guess we will see how that goes

Good old JB weld.
I've used different types of JB weld and have had good results when the directions are followed. It's a lot cheaper buying this than replacing what it was used on. Proper prep and following the instructions usually gets good results.

Works as advertised
Used between fender and apron on a1987 Toyota truck. Makes a good seal. Check your fit before applying sealer to avoid moving the panel too much after initial attachment.

Great product, nice to work with
Works very well, sets up fairly quickly so have your work well planned and prepped before applying the product. I took one star away, because it can be closed and reused again, but the mixing nozzle is a once and done, due to the material quick curing - the next use is manual mixing and application…two nozzles would make this perfect.
