Sanding & More Epoxy

Gave the hull a sand with 80 grit sand paper using the orbital sander. No real runs or rough spots and I think I have the epoxy on pretty thin. Rolled on another (4th) coat of epoxy (correct ratio this time!). I can still see some of the fibreglass weave pattern, but I don't want to put on too much. Perhaps I'll will go with what I've got and go with an undercoat primer on the hull next.
