The boat has been hauled and is covered. When I launched in the spring last year, I did touch up a few spots on the bottom, but did not do the entire thing. This fall I was pleasantly surprised too see that the paint did as advertised. The only thing I might do differently next time would be to apply an extra coat to the waterline area. I did not miss the "fun" of sanding and repainting this spring.
Bear in mind, my boat is only in the water for about 5 months, and the water temps never get past 65 degrees F. Your conditions may be different so you might have different results.
Good luck.
