Thanks man.
To be totally honest... black was chosen so I could drive it like this.
I've only seen this epoxy primer in gray or black. I had no interest in driving it in gray primer...so black it is. Plus, I used up the old stuff from 4042 before I cracked a new can. I do believe it will give a darker depth to the red once done, but I can't claim that was my primary reason.
Thinking of putting a red hash stripe on the LF fender, wheels in the same black. Going for the sinister look until it gets turned to arrest me red.
