I think the key to success with the multi-year paint is surface preperation. If the paint/hull your going over is not in very good condtion to start with the new paint will not last as long. I recondtioned my hull 8 years ago. Scraped and sanded to bare fiberglass, 3 coats of barier coat, 1 coat of red, and then applied 3 coats of black csc extra. When I see the red showing through I know where I have to touch up and I apply a cheater coat to the water line every year. I'm not saying you have to go to the extremes I did but in 8 years I've only had to paint the entire hull one time. Also, take care when power washing. Use the medium pressure tip on your power washer so you're only cleaning the slime off and not blasting the paint off.
