Making it look new
Weathered fiberglass will oxidize, and become dull. I've used Meguiars products for years, though there are others that do a nice job. Basically, you need to perform a few distinct jobs: 1) wash the boat with soap and water to remove loose dirt and grime. 2)Clean the fiberglass with a product designed to remove oxidation, stains, pollution, etc. 3)Polish the fiberglass with a product designed to add oils and rejuvenate the finish. 4)Then, wax the fiberglass to protect it, and keep it shiny. If your hull is really bad, you may need to perform all the above steps. If it's just dirty, often a wash and wax will make it look new. Check www.meguiars.com, or their catalog for full info. (Whatever you do, don't wax areas of the boat that you walk on--you'll wind up slipping.) Hope this helps.Randy
