I applied two layers to the top last weekend and was satisfied with the result. After starting, I realized that small batches of epoxy (15 squirts for me) permitted me to saturate the layers without rushing. I needed hours to finish anyway, and I suspect that applying a single layer would have been easier, so if I had it to do over, I’d try the approach they use in the class.
I had one small bubble along the edge that I could have avoided easily if I had noticed it. I may sand it, but I could also fill it with epoxy when glassing the bottom later. I’m out of town this week and next, so I’ll finish glassing the shell next weekend. My build is proceeding very slowly, but it’s proceeding. I originally hoped to finish in September, but October seems more realistic now.
