Unfortunateky not, but you can get surprisingly good results brushing
or rolling gelcoat (several coats), and then rubbing it out - working
up through the grits to 1500 or so, followed by a good buffing with
rubbing compound. As you are probably aware there are two kinds of
gel coat, one without a wax additive for layering up multiple coats,
and the other type that has the wax additive for the top coat. The
purpose of the wax is to seal out the air which prevents it from
curing all the way. It's kind of fun actually, and of course you want
to practice on some plywood first. The nice thing anout gelcoat is
that it's very easy to repair if you mess up.

I have a friend who painted his older 38' Hatteras Sportsfish as a
DIY project using the "brush and tip" technique. Came out very nice.
Smooth and shiny.

I did a 28 foot sailboat that way a long time ago using 2 part
polyurethane . It came out well but was a lot of work and delayed my
spring launch time. That's the only boat that I've ever sold for more
than I paid however.
