Thanks, Chris. The Z is not mine. I believe it is a 71 or 72, but it's not a Gen 1 (when they had 240Z behind the quarter window, not the circular Z symbol). It's an Arizona car, so very little rust. A good base for a restoration...if the garage-mate ever gets around to it.
As for the SPI red, I've read Barry saying (or agreeing to) that it is a single pigment and essentially his version of Dodge Viper red. I got chips of all of them and it was clearly different. A bit more subtle between the medium and dark, but not that one. So, slap you in the face, RED.
