The Pepsi blue PPG I used on my Vmc 27 was taken from a Prophet formula ( meaning they matched the original color. That was a PPG Shopline # 190015.
For my VMC 81 I used Dupont # 7621A
Hope this helps.
Are these codes still accurate? I called my paint supplier he had the Shop line in the system but the DuPont wasn't in the system. I know this is an old post.
