Back to anodising.........
It is a form of a coating, but one created by an electrochemical process. If they leave the metal in the solution too long, you get what is know as a hard anodise. Some insulators are made this way.
Unfortunately, if you do it to front panel that you want to be a clear anodise, it comes out yellow.
How do I know?? Guess how many times the anodisers have ruined our front panels................
