And learned (well, experienced) again that you shouldn’t mix too much resin at one time. It is exothermic and if you have a large batch the self heating drives the curing too fast,so you get a big lump of cured resin that will burn your hands. Also remember to to good brushes. I had a snag in the spatula I was using and it made it impossible to wet out the glass, so I resorted to my built in spatula and completed the layup by hand, literally. Not very good safety practice.
Tomorrow I will finish the radiator duct and mark that off this list.
