Beschreibung
Zusammenfassung:	A method of coating an aluminum wheel comprises: coating the aluminum wheel with a coating composition (A) comprising a thermosetting or thermoplastic resin having a glass transition temperature of -25 DEG to 60 DEG C. and an elongation of at least 30% (at 20 DEG C.) when in the form of a cured coating, and finely divided transparent silica and/or alumina 0.005 to 0.05 mu m particle size, in an amount of 5 to 35 parts by weight per 100 parts by weight of the resin, and subsequently coating the resulting coating with a thermosetting acrylic resin coating composition (B) capable of forming a coating having an elongation of 3 to 30% (at 20 DEG C.) and a glass transition temperature of 60 DEG to 130 DEG C.
