Abstract
A painted plastics article in the form of a vehicle wing comprises a polypropylene substrate with a polyamide or polyester coating formed by dual injection or blow moulding. The coating makes the wing suitable for subsequent painting which may be carried out on a normal vehicle paint line used to paint a metal body-in-white. To promote adhesion between the polypropylene substrate and the coating, the substrate includes an admixture of a compatibiliser such as a maleic anhydride grafted polypropylene.
