Additional information would be helpful: Are you painting above or
below the waterline / do you want to be proud of the end result, or is
this a 'beater'?

Generally, one must use an epoxy (i.e. 2-part) primer over a clear
epoxy layup (i.e. your cloth/epoxy covering). This serves to
illiminate the possibility of any amine blush causing adhesion
problems, regardless of what type of finish you subsequently apply.
Interlux 'Epoxy Barrier Kote' is one such product. They specifically
warn one to NOT use single-part primers over clear epoxy (i.e. your
cloth covering).

Interlux puts it this way: "Use Epoxy Barrier-Kote over clear epoxies
as a sanding surfacer and to eliminate the effects of amine blush."

Good Luck.
