Steve I guess that leads me to my next point/question.. When these cars came out of paint for the body color it then traveled through the next stage which was the striping and black out area. I would bet that the black used for the stripes was the same that was used for the bb blackout, rs blackout etc.. This is an interesting read and lends to some speculation on both sides but I just don't see GM using multiple blacks for the fear of creating a possible mistake.. Maybe I'm wrong..
