Re: painting steel?
I don't know about getting epoxy to stick to steel, but I do know two
things:
1) After you put on the epoxy, you are painting the epoxy not the
steel, so the same paints should work.
2) Latex paint is not a barrier to water vapor.

can get treatments for steel, maybe at a car paint place, that will
make things stick better (phosphoric acid, I think, maybe you can
soak overnight in Diet Coke). Make sure all is very clean, and apply
the epoxy right after the treatment, or as soon as it is dry. A
technique I've heard of is to further abrade the metal, with
Scotchbrite or something, AFTER you put on the epoxy, but while it is
still wet, so that nothing oxidizes to interfere with the bond. I
suppose you'd have to wipe off some of the grunge, so I don't know
about this.
I don't know if latex is going to be a good moisture barrier. I'd use
some kind of paint for metal on top of the epoxy if it was my boat.

When I talked to Payson about the galvanized hinges specified in the plans, he
said to use regular iron and coat them with epoxy and then paint. I wonder if I
need any special paint for this or if after coating with the Fiberglass systems
epoxy I have been using for the rest of the boat, I can use some of the Sherwin
Williams pro block primer and the same latex I have been using for the decks?
Any advice would be much appreciated?
