Hi Craig, I repainted our 29 footer using International two part polyurethane (?) paint many many years ago. As the painted area gets larger you need a second person to tip off the paint as you progress. .........and yes, I did have a few sags in the paint that disturbed me. However, my helper said, if you get 10 feet away from the boat you'll never see them; ........and he was right! The finish looked great. On the ComPac 16, the Car Topper and the NYMPH, I used the single part International paint for the hull, and they all look great. The two part paint may last a few years longer, but is more difficult to apply properly. After my experience with both systems, I'll use the single part paint and settle for the easier and more forgiving application. If I have to repaint after 6 years instead of 10 will I really remember; or care? Connie
