Thanks for the tips Mike.
Almost all of the epoxy was on the inside of the hull, so when I wrapped the boat in plastic I sealed it in. I tried using a heatgun, but that didn't work too well, as it heated a small area up too hot before the rest was getting the effects. After this afternoon (the "greenhouse warmed up some more, maybe to 100) the epoxy is even more cured, and seems like it will eventually finish. The mix was right, I used the supplied pumps, and the hardener was Newfounds special mix.

BTW I am getting course credit, and I don't have a fourth block class(We are on the block system, 4 clases a day), but the kayak is all mine, my own tools and materials.
