Is styrene is compatible with the epoxy for a gloss coat?

Styrene is not compatible with epoxy. Additive F is the epoxy reducer. You want to double the amount of additive F for a gloss coat to thin it out...  about 10 cc (ml) per quart of resin. The rule of thumb for a hotocat is 2cc per oz. of hardener, so it'll be 4cc per oz of hardener for a gloss coat.
