I used the vinyl and HH-66 to reinforce a Zodiac inflatable raft where the bottom attaches to the tubes. It is a 20+ y.o. raft and the factory glue job was starting to fail. I like the HH-66 adhesive and Mytee had a quart at a fraction of what the raft material suppliers were wanting. It was so cost effective I was able to glop some into baby food jars and give to friends for emergency repair kits. In fact, the vinyl was the same way. It is good quality, though not as thick as original material, and I got enough to share it as well. Expect to have to square up your vinyl once on the cutting table though. All in all I'm very please with my purchase and glad I found Mytee. I held off doing a review to see how these products would hold up. The tarp repair vinyl glued with the HH-66 has been in the Sacramento River Delta water and 100+ degrees for over a month now and is holding up well.
