I have a 2001 National Tradewinds, it is all white with faded decals. What is the best product to bring the shine back to it before I have the decals replaced?
Meguiar's One Step Compound Marine and RV. If the oxidation is really bad you may want to use Meguiar's Oxidation Remover followed by the polishing compound. This is what our RV tech uses.
I agree with above info, Meguiar's Oxidation Remover (#49 Marine-RV) is the best I found on badly oxidized surface, though I followed it with a wax or polish. The oxidation remover may require a couple of applications for highly oxidized surfaces.
