I've always wondered if Great Stuff Foam Sealant would work in this application. If you could get it done (wouldn't be easy), it might break down with use.

It expands too much.....dont ask....LOLOL

HAHA! I'd like to have seen that. :D

Used to have a pontoon boat. The pontoons would expand and contract with the cold and heat making a pretty loud boom. They had some kind of foam they could inject in there to stop that and make the pontoons unsinkable if one ran into a rock and ripped a hole in one. We never got it done, and sold the boat, but I think they put that in all pontoons now.
