Hi, I just finished fiberglassing the deck of my guillemot ( doing the deck first) I have to admit that for all my worrying about doing this for the first time everything went smoothly, I did not use a seal coat. In another half hour I'll go check for bubbles or dry spots, the MAS epoxy (cool cure) is great to work with. Applied the first coat with a squeegee and will roll the next couple of coats. Thanks for everyones help. Kenny
