There is no reason to let a layer of epoxy cure on the surface before using the composite.
I was able to remove much of the foam from low stress areas once I built it.
Develop your technique on composite before you commit your beautiful foam shell to learning a technique. Like others have said. Complete the shape before working on hardening it.

If you use epoxy resin, you should have no problem except for paying three to four more times the cost of the cheaper polyester resin which I assumed you meant when you said fiberglass. Epoxy will not attack the pink foam, no styrene in it. Polyester resin will make pink foam look like the Wicked Witch of the West after she has had water thrown on her.
