Humbrol #159 "Matt khaki drab" and #85 "Satin coal black", and Testors "Chrome silver".
The body is painted now too, I sprayed the metallic green over flat black and I have a Mustang where I have sprayed the same paint over white (to mask off the Shelby stripes), at least I think that there is kind of a difference between them, the Mustang is clearly green and doesn't change very much depending on the light, the Camaro is almost black when looked upon in normal light conditions but when it's close to a light source you see a very nice green shimmer from the metallic flakes in the paint, kind of a cool effect actually. But it needs some wet sanding and polishing.
