Going to look into that, at least for our SUPS which we need to field repair from time to time. I know some whitewater kayakers who use something like Bitchathane(no idea on spelling, I just recall te conversation about it) for emergency repairs on plastic kayaks, I guess it's some type of roofing material. Maybe related to Bitumen?BrianC wrote: ↑Thu Feb 13, 2020 3:11 pmWhen sea kayaking, we always carry some Denso tape - basically a strong fiber tape with a thick bitumen layer that sticks to the hull, even when wet. It comes in 6" wide rolls and has a plastic film covering the sticky side. Just cut off a piece, peal the covering, and slap over the hole.
Looks like it's Bituthene I was thinking of and it is related to Bitumen.
