I''m in the process of a major refit of our 30 year old sailboat. I had the same question and came up with my answers from Interlux. The technical help at Interlux is terrific. What I ended up doing is painting a two part undercoat called Interlux Epoxy Barrier-Kote 404/414. This goes on real easy but has enough odor you would have to leave the boat. Before applying the under coat I had to wash the unpainted fiberglass with soap and water and rinse well. Then I was instructed to wash the area with Interlux 202 Solvent Wash. 202 Solvent Wash is a combination of several solvents, some of which are very slow to evaporate from the surface of unpainted fiberglass being wiped. This characteristic is very important because the wax contaminants must stay in solution so that it can be wiped from the surface before it dries.
The purpose of all this washing is to get rid of the natural wax on the surface, called amine blush, on the fiberglass/epoxy/gell coat. If you don''t go to all this trouble any paint you apply will peel off over time due to the amine blush. I used the same cleaning treatment for the wooden parts, which was probably over kill. I then used a one part primer called Intelux Pre-Cote. I then used Interlux Bilge Coat as the top coat over the entire project. This paint goes on so easy and looks great, is tough, and perfect for the locker areas. I can''t say this is the only way to approach the task, it is the way that seemed most reasonable to me. My intent was to never have to do this again. You can go to Interlux''s web site at http:\\www.yachtpaint\com\us.
