I would agree that on any drysailed boat, pretty much any paint can be used.
I have used some automotive dupont polyurathane that has held up great on a hobie 16
I have used a variety of interlux paints- I am not the best at applying them, but they are pretty durable.
The other paint to consider- especially if you have someone with good spraying abilities- is aircraft paint. I don't know of anything more durable.
