An alloy wheel is formed having a three dimensional configuration defining a face and recessed surfaces. The face of the wheel is machined providing a smooth surface at the face and defining an edge between the smooth surface of the face and the recessed surfaces. A nozzle element for projecting a plasma jet toward the wheel is provided. The plasma jet is projected toward the smooth surface of the face, the edge, and toward at least a portion of the recessed surfaces forming an alloy oxide at least on the face and the edge disposed between the face and the recessed surfaces. A first polymeric coating is applied over the face, the recessed surfaces and the edge disposed between the face and the recessed surfaces.
