Doing a 2 tone job on a 78 GMC 4x4 (green upper and lower, white center) , and looking to spice up the white just a little.........Ive found a bunch of whites i like that have a hint of silver or gold in them, which is fine but I'm looking not to do tricoat and thats what they all seem to be. Im painting the cab and bed at different times so worried about matching is all. Didn't know if anyone has a familiar code or something.
