Hi, Do yo use wheel cleaning sprays/chemicals?? Don't. Do you use a pressure spray/washer? Don't - not only does the spray perforate the tyre it increases the wear on the wheels and their finish. If the wheel is corroding from the inside - causing the paint and lacquer to peel then the wheels need to be brought back to the metal, acid etched and maybe zinc treated to prevent further corrosion. Then apply the paint and bake, and then clear coat/lacquer and bake again.. Des. . . ;)
