I have a badly oxidized 25' Hunter that needs some TLC. I just bought 3M Marine FiberGlass Restorer and Wax, but after doing some research I feel that PolyGlow is a much better product.Can you onyl buy PolyGlow on-line? I live in Michigan and did not find it on West Marines site.Any tips for severly oxidized hulls with PG? I get an excessive amount of chalk residue when rubbing the hull.Thanks!!
