Wax in polyester is used to allow seal the resin from the air to allow
the resin to harden without a sticky surface. If a getcoat is used as
the first layer in a lay up schedule there is no need for wax.
I haven't checked costs but I'd guess that the resin containing wax
might be a bit more expensive then the untreated stuff so logically a
factory would use "un-waxed" resin when using get-coat.

hmmm.... then it would make sense to use "un-waxed" resin for the hull
(hull definitely has a gel coat exterior) but wax in the resin for the
seats. The finish on the seats and interior hull are sprayed on after
they both came out of their respective molds. That would explain my
problem perfectly.

Without seeing anything except photos I would suggest that you grind
or sand the areas where the finish has failed until you reach a solid
surface, regardless of what the material is. Then if you are worried
about the fiberglass absorbing water, you can paint on one or two
coats of activated epoxy resin. Finish by applying two coats of high
build epoxy primer, sand, do any minor fairing with epoxy or polyester
filler, and finally spray on two coats of two parts polyurethane.

Sounds like a plan.
I'll probably just do the seats for now. They won't match the bottom
and sides exactly but I think I can make it look ok. And hopefully it
won't peel off again.
Thanks y'all :-)
