Bill, will this work on thermoformed boats as well as the rotomolded type you worked on, I believe the thermoformed boats are an abs material. It is quite a bit thinner than rotomold best inflatable kayaks, but lighter and some what similar in strength, but would suffer a bit more in rock gardening. Just wondering if the tarp material would stick, and be a good keel reinforcer. any info would be helpful, Thx! P.S. This repair looks easy and strong! Very cool!
