This was a very distressed boat. I had a cover that only covered the upper part of the hull, exposing the lower part to the elements. On top of that a hurricane ripped the existing cover off and the boat sat exposed to the Florida sun for several years. Both the topside and hull experienced extreme oxidation. The hull had to be wet sanded several times and the topside buffed twice. The hull also had to be buffed and waxed. The good news is, the boat came out looking like it did in 2007.
