FWIW, Stefano had a car a few years ago that was later sold as a prepped roller that was completely finished in primer/sealer. It was a yellow on yellow RS Z/28 and the floors were finished much how this car was found with a lot of gray original primer and lot's of yellow overspray in the rear of the car. Mine appears to have even more yellow up in the tunnel but the grey primed base is nearly identical and there does not appear to be any black other than the lower floor plans, the transmission tunnel area. Some sound deadener is also applied to the back wheel openings and was over-sprayed along the rear frame rails between the time the floors were done and the body surface was sprayed. Firewall was of course black over yellow as stated earlier

Here are the pics of that other yellow on yellow car.
