PPG Minor Repair Process for Mazda Paint Code 46G Machine Gray

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 it's 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. This specific minor repair process is best suited for small to medium-sized spot repairs. The process outlined in this document is necessary to meet appearance, performance, and VOC regulatory requirements. You should contact your PPG representative for full documentation on the approved products, systems and processes.
