Mazda paint code 46G Machine Gray is a special effect gray metallic color that gives the paint a “sculpted from solid steel” appearance. The OEM process utilizes an exotic tri-coat system made up of a black color coat followed by high brightness leafing aluminum layer, then is topped with a clearcoat.

Given this unique clearcoat finish, and its relatively thin film build, the procedure for performing quality repairs of this color differs from PPG's normal waterborne basecoat system process, especially in how the surface is prepped, and how the basecoat is applied.

The repair processes in the videos and technical bulletins below are intended to replicate the OEM finish as closely as possible utilizing products similar to those at the factory.
