The polyester/styrene based resins will dissolve the foam. Once it's coated with the epoxy (with or without glass?) then you could use other resins, I would consider the Duratec Sunshield. It's UV and specifically made to coat over epoxy or other resins. If you want a clear? If you don't need clear then it could be coated over the epoxy coat with with a polyester flow coat to any colour you need. Tough and durable. You might want to do your own small sample just to test the adhesion between the epoxy and a polyester. Fastacraft Facebook page Edited 9 Years Ago by Fasta

But I feel generally that epoxies are mostly not much good for UV/gloss retention so a gloss finish will not stay glossy for long if exposed to much sun.
