To protect myself from fiberglass particles, I zipped on a white Tyvek suit, put on a respirator and ear protectors, and went at it. Here I made the mistake of grinding with 5-inch discs of 36-grit sandpaper. I should’ve used a grinder capable of carrying 8-inch discs sitting on a soft pad. Better yet, I should’ve hired someone to do it. I did remove all the dry fibers but, due to the small disc, the surface still needed fairing. I troweled on epoxy resin thickened with colloidal silica, both WEST System products. This had to be sanded before rolling on coats of Interlux’s InterProtect 2000, an epoxy-based barrier product. First, I washed the surface with water and light detergent in order to remove the amine blush, a waxy film produced by curing epoxy. A 44-foot boat with a long keel, a 32-foot waterline, and a nearly 7-foot draft towered over Nancy and me like a cliff of cured epoxy as hard as granite. The task of fairing it all with orbital high-speed sanders, followed by wet sanding, took us three long days.
