I was wondering if anybody has any good methods for repoducing the red/brown underbody primer used on GM cars in the early 70's.I want something that will hold up to abuse of normal useage,and even racing,but look original.I was thinking of mixing some POR15 topcoats until I matched what is on my car now{it has most of the original primer but is loosing it fast}.The car is about 50% complete,so going back in for a sandblast isnt an option.I know most guys around here dont think about building stuff to "abuse" it,but I am restoring a race car and want the finished product to look like an early 70's era pro stocker built off of a new production car.I then plan on running the stink out of it every weekend in the 10.90 and electronics bracket classes,so durabilty is key.Thanks in advance.
