A metal workpiece, such as a wheel, and a method of providing an enhanced corrosion resistant surface coating on an exposed surface of a metal or alloy substrate (such as magnesium). A corrosion resistance basecoat is formed, including generating an oxide layer, and applying a first primer coating onto at least a portion of the oxide layer. The method may further include identifying highest corrosion prone areas on the substrate and designing a support rack that avoids contact with these corrosion prone areas. The method also includes forming a topcoat over at least a portion of the basecoat, by applying a second primer coating onto at least a portion of the first primer coating and depositing a sputtered metallic film onto the second primer coating using a physical vapor deposition technique. A clear coat layer may be applied over the metallic film.
