Try a Single part Epoxy Paint
Try a single part epoxy paint here there is no reason to go two part for a project like this. Petit Eazypox is my favourite, goes on very nicely.
A friend just painted a 40 ft trawler with it by hand in a very dark blue. Looks really good. Not pefect but all shiny and nice. Much cheaper and easier to use than the two part paint.
