jb weld

[slingshot]

have a stress crack in the back of my livewell that is about 6 inches long. it is in the weld that was put there to form the livewell when it was new[1985]. was thinking of trying jb weld on it but haven't had to much sucess useing it on my buisness equpiment because it flexes. has anyone tried it on their aluminum boats?

I think I would try urethane caulk before I would use that. I think it would work better for you, or check on 3m's 5200 caulk. There are alot of people using it for salt water use on their jack plates instead of silicone caulk.

I have used it to seal cracks in fiberglass, steel and aluminum. I even repaired a leaking crack on a hydrolic fluid tank of a log splitter. I prefer the JB Weld putty stick. Green on the outside and white on the inside. Cut off a piece, need it between your fingers till it becomes one color and fill in the crack. It dries very quickly so fill it fast. Make sure the surface is clean (absolutely no grease or oil) and rough up the surface with a grinder. When sealing a live well, I put it on the inside and the outside of the cracked tank. I find it to be amazing stuff. Good luck.

^ What he said to a T.

was told that if it failed or did not work that the repair would be more because it would have to be removed[the jb weld]. I was also told that to weld aluminum it needs to be warm for the weld to take. If I had to wait on that I will be fishing in may the way things are right now. Any welders out there that can tell me if that is so?

I would for sure take River Hawk's advice

Im a welder and have been for 23 years. It doesnt have to be warm to weld alum.But I will try that line next time I have to weld and it snowing.lol Alum has to be clean,dry and out of the wind to be welded. The weld probably failed due to vibration the first time.Was probably weld on the outside corner only because if you weld the inside of a corner joint it will warp some due to heat.I use a product use sonicweld which is available at most partstores.The good rtv will work also. I would use Jb weld due to the vibration cause jbweld doesnt flex too well. If it was mine I would and it was hard to get the livewell out or hard to find a welder I would use the rtv or sonicweld and try it.Heck if it dont work you will have to pull the livewell anyway.Be sure to clean all paint and scuff the area.Spray with ether it is a good cleaner. Watch for sparks.Maybe this will help.

Don't know about jb weld, but I had a rivet knocked out on the bottom of my bass tracker. I bought a product called Marine Tex and placed over the hole. That was three years ago and it has yet to leak.

that is the problem. the livewell is rivited in and I only have one shot to do it right or I will have to drill out the rivits and pull it. the back of the liviewell is hard to get to without pulling off the back deck which I may have to do anyway so it can be welded. Thanks for everyones input.
