Rare LS6 - restoration to begin - question...?

[NEATSS]

How were these special paint cars handled at the factory? I have seen 3 unrestored hugger/monacco orange LS6 cars over the past 20 years. The first one I looked at very carefully for signs of a repaint. It had the - - cowl tag. Inside the trunk on the torson bars for the hinges it showed gobi beige(code 50). It had a shine where it was not covered with orange overspray so it was not primer. Were these cars painted a neutral color on the line and then pulled off the line and topcoated or was this car just a freak?
