"All of the ARC catamarans use Sherwin Williams Auto Paint. East maintenance and UV properties. "
And quite expensive too! Also not your simple rattle can application. Of course I wouldn't paint an entire boat with a rattle can anyway.
The ARCs have an Awgrip 3 part primer (paint, hardener & reducer) and the Sherwin Williams 3 part top coat. While the finish is excellent (I can still see a clear refelection in my paint 8 years later), it is probably overkill for an old Nacra 5.2.
I plan to paint my Nacra 5.2 with some enamel paint I bought from home depot. I asked the paint guy what to reduce it with so it will work in the paint gun and he showed me the reducer. It's a lot cheaper than $75 a quart.
I'll post back here when I finally paint it. Right now I have a lot of work on the RC-27 to do.
