Default Refinishing questions

Hello,

The shop I was surveying the other day uses Sherwin-Williams urethane,
they have all bells and whistles, but when I asked about how they're
planning on doing a fiberglass ship
the manager said that they'll "shoot it and then put it into the oven
for some time to cure" just like
it was a truck
According to Randy Lervold http://www.romeolima.com/RV8/Paint.htm you
can shoot PU with a bit
of preparation.There is a certain amount of preparation needed but as

any other paintjob needs good preparation.The only thing I don't like
with gelcoat is that it cracks;
however-will it really crack so bad on a refinished 20 year old glider
as on the new one if you keep it
in the trailer? In other words: how many of these cracks are stress-
imposed and how many by the resins being cured?
(and shrinking/warping of the parts)

I wish I could fix the hinge somehow, but I'm glad to hear that
they're replaceable.

Thanks,
