Thisd sounds correct- but--- Epoxy doesn't cure with UV, just faster with heat, assuming close to the proper ratio between amine and epoxy has been mixed. You are supposed to wash off the amine blush then sand it. The dogma is to then use epoxy with fumed silica gel= gelcoat. (PS: It yellows)

Polyester does cure with UV- or ozone + air inside the unused can, eventually. But it doesn't do well on top of epoxy.
