Car materials - Eevee

I’m currently working on a set of materials for cars, the set includes:
-Car paint with support for dirt, damage and paint effects
-Carbon fiber with support for top coat
-Rubber with support for damage and dirt
-Glass material with support for shade percentage, damage and dirt
-“Perfect Alloy” for chrome, gold and other metal pieces

All materials are for Eevee and will be released as they get finished
