Im wondering if anyone can Shine some light on this subject. <br />Ive read that Carnauba Wax will yellow a fiberglass boat over time, yet allot of boat wax is made from this stuff. <br />Have been searching for a good marine wax that will last more than just a few times out and not yellow fiberglass. <br />I can really see an improvement in speed when I first take out boat after waxing,but it doesnt last long.<br />Can anyone recommend a good marine wax that will last more than one or two trips out ? What does everyone else use ? <br />You do wax your boat.. right?
