I thought I had already rated this product but maybe it was different tube size. Everything that needs to be said about Aquaseal has already been said. I have used it for John Deere riding mower seat, fishing waders, boat seats,  and sealing hydroturf boat flooring products. This is a great rubber like compound. Be sure to keep big tubes in freezer or covered container to make it last. I use a zip lock in my fishing vest and freezer for my large tube supply in my garage.
