hey all, i have made a fiberglass mould with a gelcoat base.  the mold turned out pretty good, i had to fill a few voids with glass and resin. i waked it 5 times with carnuba wax, then i laid a layer of epoxy resin and then a layer of carbon fiber.  i repeated this step 2 times.  when  i pulled the part out the front side is very dull while the back side is extreamly glossy.  what would be the best way to get the high gloss on the front of the part?  should i not use PVA?  thanks for the help

Got some photos?
Either your mould surface isnt glossy or you didnt polish off the wax. Have you polished the part after demoulding?
