I used a cheapy 6 inch polisher/buffer (auto polish section) and 3M Fiberglass/gelcoat restorer (sporting goods boat stuff section) both from walmart. Cost a grand total of about $25 and brought a great shine back to the finish on mine. Dont use anything with a high rpm in a circular motion as you'll burn through. <br /><br />Hoping someone with more experiance will chime in here.
