Sealing, Filling and Painting
Step 1. Our Aquasport had a number of laminate voids, plus some userinstalled gouges. Fill imperfections with Watertite Epoxy Filler. Using a spreader or putty knife, swipe the goop across the gouge and then scrape off the excess from several directions. Two applications might be necessary - don't try to fill all in one pass. Overfill slightly, then after two hours, sand it flush with 80-grit paper and a sanding block, followed by 120-grit.
Step 2. Wipe down filled areas with 202, as epoxy "blushes" with a waxy film upon cure that will retard adhesion of bottom paint.
Step 3. Mask off the waterline and any underwater metals, including drive housings, engine-mounting brackets, through-hulls, swim ladders and trim tabs. Mix the paint thoroughly.
Step 4. Apply bottom paint. For best results, use a 3/8-inch nap roller cover, cutting in around fittings, drives and engines, struts, etc., with a chip brush first. Apply a minimum of two coats. We chose an ablative paint instead of a "hard" coating, since these wear away evenly in use, largely eliminating the need to have to strip down to bare 'glass in the future.
