I used the term "gelcoat" as a generic word for epoxy applied before applying the glass. A real gelcoat is resin applied in its normal state and then allowed to gel up on the mold. This reduces print through of the cloth to the finished surface. In my case, I don't let the epoxy gel, I just go straight to adding glass. I would get a smoother surface if I let the resin set up a bit after applying it.

: I applied the epoxy immediately after mixing - I didn't wait for it to gel.
: You wouldn't get good penetration through the glass if you did. Nick, just
: what did you mean?
