Re: Paint
Before we get into the paint aspect, I have to ask about the boat itself. You say it is fiberglass. In that case, what is the condition of the gel coat? If the gel coat is simply oxidized you can buff it back to almost new condition. This would be much easier and less time consuming than a total re-paint. I did my 16 foot Sea Ray in a day including removing rub-rail, cleats, bow rail, etc. You can see a few pictures of the results at this
link. Even gel coat more heavily oxidized than mine can be brought back to life with wet sanding before the buffing.
As for paint, most any paint can also be buffed to look great. Buffed Rust-o-leum looks outstanding believe it or not. I heard about guys painting cars with Rust-O-Leum and decided to do a little experiment with it a few years age. I had an old car door skin and painted it with rust-o-leum and after 7 days cure I buffed it out. I have to say the results were pretty amazing. I intentionally used a red color close to the color of a 1970 Mustang I had restored. I have to say that the rust-o-leum panel looked every bit as good as the 2 part urethane paint on the Mustang. I can't say it would last as long, but I kept that door skin outside of my barn for a few years and the thing still looked great when I finally decided to throw it away.
