So this was the real reason for this topic! I had this self bailing floor (PVC) in my garage, and the floor on this raft was in such poor shape. So I was trying to decide if I needed to carry 2 patch kits, one for the floor and for the tubes. Thanks all for the advice, I'll be going with hypalon material since I have a lot of it from my floor, and stabond glue that should work on both. Thanks again!
And I realized after I laced it in that I should have the floor on the outside of the raft material, I'll fix it. It'll be a couple weeks before it's first trip
