摘要： Disclosed are methods of forming a multiple coating on a dry plating member and a molded article manufactured using the same. The method may include applying a color coating agent onto a surface of a plating layer of a plating member and then drying the applied color coating agent to form a color coating layer, and applying a clear coating agent onto a surface of the color coating layer and curing the applied clear coating agent to form a clear layer, wherein the plating member includes a substrate, an undercoat layer formed on a surface of at least a part of the substrate, and a plating layer formed on a surface of the undercoat layer.

摘要： The present invention provides a variable aerodynamic system for a vehicle. The system includes an active air skirt, an active rear spoiler, and an active rear bumper spoiler of which one or more are selected and deployed by a controller, while a vehicle is running, when the controller receives information obtained by a detector, and determines that the obtained information satisfies conditions inputted in advance by comparing the obtained information with the conditions inputted in advance. The height from an end of a front bumper to a front wheel center is within a predetermined value.
