I’ve been struggling with the epoxy fill coats. Lots of bubbles, and an uneven coating. I left the garage heater on by mistake today and when I got home it was 85F in the garage. I put a coat of epoxy on and it’s smooth as glass. It was about 70F when I put the other coats on. Also, I didn’t have near as much trouble last year, but I was applying the epoxy in the summer time.

I’m using System 3 with slow hardner.
