im putting fibreglass cloth with epoxy resin on my boat and wanted to
paint it, but i dont know if i have to use primer first or just add
the paint? any help would be appreciated, if i use primer, which type
do i get? thanks,
Jason.

Paints such as Interlux Britesides are commonly used directly over epoxy.

Still, it may be wise to adhere to the manufacturer's recommendations,
which for Interlux brightside reads:

CLEAR EPOXY: Clean as for Bare Fiberglass. Sand with 80 grade (grit)
paper. Remove sanding residue. Apply one coat of Epoxy Barrier-Kote
404/414.
