I just got the old suspension out of my R-Code Mach restore. The car has never been touched aside from some bad quarter work and some new paint over the years. However, the fire wall area and fender aprons have never been touched. As I sanded/scrapped away the paint, rust, and factory undercoating I can see the original color. Is this the original red oxidized primer in the picture attached? You can see it pretty good in the upper left. I have a color vision issue, so it is sometimes hard for me to distinguish shades. Thanks for any help.
