Abstract

This invention provides a surface conditioner for aluminum wheel comprising 0.01 to 10 mass % of a molybdic acid compound and 0.1 to 30 mass % of sulfuric acid and having a pH of less than 1 and a mass ratio of said molybdic acid compound to sulfuric acid within the range of 0.01 to 1 (former/latter), and further provides a coating method of an aluminum wheel which comprises treating a degreased aluminum wheel with the surface conditioner as mentioned above, washing the treated wheel with water, chromating the same at a chromium coverage of 1 to 10 mg/m2, washing the chromated wheel with water, drying the same and applying a clear coating.
