I'm not qualified to answer the question about paint v. gelcoat. But
everybody seems, for some reason, going the Awlgrip route. We just
had #41 Awlgripped, and it turned out really well. Another
interesting question is spraying Awlgrip versus rolling it on. We had
ours rolled, and it turned out beautifully. I have heard some people
claim that rolling it on produces a glossier finish than spraying.
Also I have heard that there is somewhat of a learning curve in
rolling technique (from the guy who painted our boat). I looked at 5
or 6 boats rolled by our painter, Tim Sarns, and his earliest ones
weren't as good as his more recent ones. Rolling the topsides should
be less expensive than spraying and isn't as hazardous. I don't know
about gelcoat.
