After three years of owning our Legend 37.5, we need to repaint the bottom. She lives in the northern great lakes, so the bottom lasts for 3 years. We will use VC-17 as that is what is already on the bottom. The bottom is not in bad shape - no paint is pealing. It just appears that the paint is thinning out or wearing off, which is what I believe it is supposed to do.Based on my research to date, the appliction instructions are to clean bottom, sand any loose paint, and roll or spray on, thinning as required. While this does not look difficult. I have a couple of questions. First, the insturctions say use 2-3 coats. Does this apply to a repaint job where there already is a coat or two of paint of the bottom? Secondly, does anyone know how much VC-17 it will take to put one coat on our Legend 37.5?
