QUICK FIX from, (((((Leon)))) Use WENOL metal polish (yes metal polish) on the gel coat of any boat to cut through the crap and restore lustre. It is available through summit racing and will run about $35 per can. A can will last you for 4 or 5 whole boats and then some. Now here's the trick: Just make sure you don't use very much of the polish or it is hard to get back out of the surface. A little ol dab will do ya. I've never used it with a wheel but i think it would work even better with a wheel. Apply by hand and then rub out by hand or with the wheel. Good Luck.
