    摘要: A method of manufacturing a body, preferrably an automotive vehicle body, to have a plurality of coating layers, starts with assembling the body out of parts made from pre-coated metal. A pretreatment step provides for paint adhesion and/or corrosion protection for cut edges, weld spots or metal finished areas. A powder paint base coat is then applied onto the pre-coated metal of the vehicle body. The pre-coat layer is one of the plurality of coating layers and the powder paint base coat is another one of the plurality of coating layers. In another embodiment, the powder paint base coat is applied in two steps, a first powder paint base coat and a color powder paint base coat. The first powder paint base coat is applied to a first portion of the vehicle body and the color powder paint base coat is applied to a second portion of the vehicle body. Unused first powder paint base coat and unused color powder paint base coat are both reclaimed, mixed, and the mixture used for at least some of the first powder paint base coat applied to the first portion of the vehicle body.
