I think the advice to match the speed of the hardner to the temperature of the resin and work area was right on. Last year I tried to speed up the fill process by using fast hardner on a hot day. It went on well but then developed an orange peel look when it cured. This year I've been using S-3 Slow hardner on 70F days, after cold nights, and I've been getting a lot of bubbles. When I warmed the garage up to 85F, it went on great.

Thanks again for the help. I'll probably warm up the resin in warm water if it's not up to 80F here in SC when I put the hull and deck together next week.
