Robert,
Pardon the truncated quote.
Just to be clear. While I don't know much about the chemical makup of epoxy primers or paints, in the world of composites epoxy and vinylester do not play well together and should not be mixed. I am specifically referring to repair products, not paint products (beyond my area).
On the FFR body, you can do lower strength repairs with polyester, but you should stay away from anything epoxy based. The gelcoat on the FFR body is polyester. I suggest seeking specific primer advice from one of the many experts on FFR body prep.
Sorry if I sound argumentative, it just that this is one peculiar thing about the FFR body that makes it different than just about all the rest.
