Most of the experts say it isn't cost-effective, particularly with the
durability of the 2-part epoxy paints.

I don't doubt that what you say is true, however...

It seems to me that if the manufacturers could save a bit by
switching from gel coat to Imron or Awlgrip they would.
Yet the boat manufacturing industry uniformly uses gel coat
instead of paint.

Professional fiberglass repair places also routinely respray
the gel coat and then buff it out.

There is little cost difference between the materials, and
the preparation is similar.

Could it be that the popularity of two-part paints is
because they can be applied more easily by the DIY crowd?
