After a couple of years searching for a product to "shine" a badly faded fiberglass top, I finally found an easy to apply, effective product that cuts through the oxidation and puts some temperory protection on the top. The product is called GEL-GLOSS. It's the best thing I've tried. I follow up with whatever car wax I have handy or Johnson's Paste Wax which lasts as well as anything.
It can be found at RV centers, marinas, even at Lowe's or other home centers. or even on-line. The most convienient spot for me was Lowe's as it can be used on fiberglass/plastic tub surrounds also.
