I would not doubt that a few were sprayed with the wrong paint... there were multiple blacks (blackout, lower dash semi-gloss, upperdash ZERO deg +TUXEDO) in the touch up booth and 2 reds as well. The red D90 stripe on a 69 Camaro is the Corvette Red from 1969 not Garnet.
As an aside... the White stripe on the Front end (Chevrolet Assembled parts) of the Black 04C survivor does not look to be the same as the white stripe on the Fisher built body, the front end is Brighter white.
