You might not have waited long enough after the acetone wipe, before applying the epoxy-acetone. It will continue to evaporate right thru the applied coating until it's gone or the coating gets hard.
Painting on epoxy is a frothy mess. However, the air bubbles in mine quickly worked their way to the top and dissapeared. My workshop was about 52 degrees F, and the epoxy set up very slowly.
I did have some remaining pinholes, but I brush coated with PPG DP-50 primer, that took care of it. My paint supplier said to just use the DP primer, but I over did it as usual. I used uncut epoxy in the bottom cowl, and acetone cut epoxy in the top cowl.
