摘要： PURPOSE:To facilitate the color matching between the main body and the plastic parts by fixing the plastic parts previously applied with a primary coating and an intermediate coating in another line to the main vehicle body with an electrodeposition coating, and then carrying out intermediate coating and finish coating in the same line. CONSTITUTION:When the main vehicle body 5 made of a steel sheet and the plastic parts 1-4 to be integrated into the body 5 are coated in the same color, the plastic parts previously applied with a primary coating and an intermediate coating by the intermediate coat capable of being used for both resin and steel sheet in another line are fixed to the vehicle body applied with an electrodeposition coating, and the intermediate coating by the intermediate coat capable of being used for both resin and steel and finish coating by the top coat capable of being used for both resin and steel sheet are carried out in the same line. As a result, the color matching between the vehicle body and the plastic part is facilitated. In addition, a finish coated film is formed on both the vehicle body and the plastic parts with good adhesion, and thermal deformation is not caused when the plastic parts are coated and baked.
