Re the "metal-flake" thing...here's where I'm at. I've got fBm nodes feeding into a color_ramp node, which is using a cellular node (although that's in no way crucial, it's just what I used) as its input...the output from the color-ramp goes into Specular_Color, mainly because it gives some degree of control over the eventual blending with templargfx's basic setup.

Comments are extremely welcome as I know bugger-all about cars, and even less about the paint jobs they get. ~lol~
