If you look at the known Chevrolet information, the -- is known as a stripe delete paint code. But the -- is also a non-standard color which might be from another division of GM or even a custom color like the Carolina Blue. The -- paint code is not an obvious designation for "special paint". Please go to
www.camaros.org and read up on it and you will understand what I'm referring to. Maybe on a Judge it meant a non-standard color as well. Nothing is obvious about it so why make a statement like that.
