Re: painting on top of epoxy resin
hey, ya i've done this (kinda...)
what I did was
1) fist, the first coat of resin over top of the painting
2) sand down the surface with finish sandpaper (black fine paper)
3) paint on top (the sanding will take away the gloss, and even look white a bit, but don't worry...)
4) add a SECOND COAT OF RESIN
that is the twist to what you are saying...
if you don't mind losing some gloss, you can sand down and the paint will stick really good and you wont need the second coat of resin...
hope that helps.
artresin is great. check it out the site has videos and a big faq that helped
