A big Gorilla
Last summer I somehow got a big abrasion on one of the tubes of my SOTAR. It wasn't losing air or anything but needed to be protected. As a quick fix I patched it with two layers of Gorilla tape. Here it is, boating season, and the tape is still bonded solidly, probably better than when it was put on! I'm going to put a real patch on soon but it shows how good Gorilla Tape is. Forget duct tape, I have a roll of Gorilla Tape in my repair kit now!
