Gelcoat over epoxy?

It is a high blush epoxy. Anyway. No matter which epoxy you use. You can still gelcoat. If it is a blushing epoxy like west then make it blush, That means forcing the amine solution out rather then it coming to the top later and lifting the gel coat. I used to gel coat west system all the time. Then lightly sand and gelcoat. Now I use much cheaper USComposites epoxy and have never seen it blush in 10 years.
