After giving the boat a day off for the epoxy to cure, I lightly sanded the epoxy coat on the deck today with 220 grit twice. I then built up the epoxy layer with a second coat. The second coat is quite a lot smoother and really looks great.

Hard to believe this is just epoxy coats over a 220 grit surface. Look at the reflection of the bicycle in the second picture. That will be the last epoxy coat. In a day I'll block sand through 220 and 320 grits and then start applying the clear to the deck and the sides.
