fastbanshee8 Posted January 10, 2010 Report Share Posted January 10, 2010 It's not the gas that's the problem, it's the two stroke oil mixed with it. When I used it, the JB Weld stuck well, but after getting a fair amount of gas, and two stroke oil on it, the JB turned into a silicon type substance, which was worthless for my needs. The local engine builder won't use it, because he's had the same type of problems as I have. There are some types of epoxies that will work, but from what I've saw, JB Weld isn't one of them.

Rotax Raptor Posted January 10, 2010 Author Report Share Posted January 10, 2010 ok man i never tried any oil on it so ill take your word for it. lol This has turned into a rather interesting topic. Since I started this, I will contact the maker of jb weld and have them give me the low down and tech data on it. Sounds like it may be good to know.

Sounds like it may be good to know. yes it has.there are other products of a more industrial strength.i work in paint and body and know about different products.there are very very good 2 part epoxies on the market that might suit your needs.these epoxies are so strong and durable they actually use these epoxies to glue quarter panels on cars with instead of metal weld and have tested stronger than metal weld in crash test.newer cars are actually glued together-(for the most part)instead of weld because of the strength.the 2 best to look into are SEM products and FUSOR products.ill check to see whats not soluble in gas or oil,if they have it.id put money there before jb weld.

broncbob Posted January 10, 2010 Report Share Posted January 10, 2010 I happen to know where there is a banshee gas tank that has the pingle valve glued in with JB, and has been for better than a year with no problems. I happen to own a diesel fired heater that the drain plug is sealed to the tank with JB, and I have had no problems with it. I know of some heads on a 455 Pontiac based engine that has repairs done to the port work with JB. Maybe it's the type of oil you use? The quad in question with the glued in pingle uses nothing but Klotz. But the list of fuels from above runs the gamut, from race gas to diesel. The stuff is good, but only as good as your prep work. I have never had it fail me on any application I have used it for, and there has been some strange stuff come up. The only issue I see with using it for the original question at hand is, how well you are able to prep the area to be sealed. If it was clean, and roughed up enough, it should be fine. The only other way to repair it would to be to weld it, and it doesn't sound like a option here. I would look into it, as I know you can weld cast aluminum, and port work is not cheap. Devcon is the shit, but it's expensive, and harder to find. Quote Link to comment Share on other sites More sharing options...
