The GT 40 was painted Guardsman Blue with Wimbeldon white. These colors were used on the Shelby Cobra 427 as well as several GT40s. Tell your painter those color names and the codes should pop up. If not let me know and I will dig a bit deeper.Loving this build thread Chuck! Lovely work. As an aside, I'm building a Mk1 GT40, and am going to finish it in the same metallic blue as yours. What paint code did you use?
