I painted the Hulls on my 16 last winter and I used a marine paint made by interlux called toplac. This paint is marketed as a paint/lacguer combination all in one. It requires no mixing. it is a little pricey but it comes out nice and glossy and has been pretty scratch resistant overall. I was only able to find it in quarts and I used about a quart and a half per hull using an air sprayer.. It does go on smooth with a brush as well although I only reccomend brushing for touchups because if you apply the paint with a brush to the whole hull you will use twice as much and end up putting a lot of weight on the boat.(which was a concern of mine.) I put it through an air sprayer with no thinning at all and it covered really well. the only thing that could have been better would have been to use a gelcoat, in my opinion.. I have sailed this boat hard all summer and the only real obvious paint damage was to the bottoms of the hulls where I would drag it across the sand. Other than that it looks shiny and new as the day I painted it.. Another helpful tip is to wax the hulls real well using a good car wax after the paint has dried.. this will help it resist scratching even more. The painting of the hulls was the easy part the bitch of the whole thing was sanding both hulls. Good Luck on you project I hope it turns out well for you.
