I've got a 20' Gulf Coast boat and the paint on (parts of) the deck is
peeling and flaking. I thought it was "gel coat", but my mechanic says
it's an epoxy paint. I'd like to redo it myself, if I can.

The fiberglass underneath is stable and intact; no problems. But the
paint on the top is flaking off.

What procedures should I follow to fix it? Should I just scrape off
the flaking stuff and sand it smooth, then paint?

Which paint should I use?

And am I heading in the general right direction?

Any help is appreciated...
