The last boat I owned I painted from top to bottom. Was it a job sure. Although once done the yearly maintenance was just like owning a four wheel vehicle. Wash it in the spring throw a quick coat of wax on it by hand and launch. I have to wonder yearly cost to have boat buffed and waxed compared to having it painted when first bought. Also when is space age technology coming to boats such as in the automotive world? The one step polymer coatings showing up in the automotive world for instance.
