I am building an Arctic Tern and so far so good. I don't think I'm going to be able to finnish the kayak with the amount of epoxy supplied. I have a marine store close to my house which sells epoxy systems by a couple of different manufacturers. My question: Is it ok to use up the epoxy that came with the kit and then switch to a different manufacturer's epoxy to finnish the boat? Will it bond properly? Will it effect the color of the boat?
