What's the best product for waxing a van with salt air damage? - waxing in hawaii

Two years in Hawaii (salt air), I left my car in a very bad condition. Is there anything on the market, homemade or something that I can use the traces of clean water spots from windows and painting? The normal cleaning does not matter.
