The step being performed in a state where a wheel body is fixed to be prevented from rotating around a rotation axis while a cutting edge of a cutting tool is in contact with the three-dimensional shape surface of the design surface in the wheel body, the cutting tool being three-dimensionally and continuously moved relatively along the three-dimensional shape surface while being changed in direction with respect to the three-dimensional shape surface to allow a rake face of the cutting tool to face a tool travel direction to perform three-dimensional continuous cutting processing that allows a specular glossy surface to be automatically formed in the three-dimensional shape surface, the specular glossy surface being finished into a processed surface having a high metallic gloss property by exposing the base metal.

A cast wheel having an alloy substrate includes a primary surface and a secondary surface. A first polymeric coating is applied to the primary surface and to the secondary surface sealing the cast alloy wheel within the first polymeric coating. An intermediate polymeric coating is applied over the first polymeric coating. The intermediate polymeric coating is coated with metal using physical vapor deposition with the metal being aesthetically distinguishable from the first polymeric coating. A third polymeric coating is applied over the metal. The third polymeric coating, the intermediate coating and the metal from the primary surface of the cast alloy wheel are removed aesthetically distinguishing the primary surface from the secondary surface. A fourth polymeric coating is applied over the primary surface and the secondary surface.
