Looks great. The Highland Green Metalic paint was a factory color for 1967 and 1968 on the Mustang and a few other models. There is a super book with every detail on the Movie Bullet Mustangs, for example the chrome mirror and the chrome strip bellow the doors were painted the body color so there would not be a light reflection into the cameras.
Sometime in the last couple of years one of the original Mustangs used in the Movie was found in TN (IIRC). I think Steve McQueen's son has one of the original movie Mustangs, but this may just be a rumer. Anyone know for sure?
I had a discussion with the Ford chemical engineer who had the task of making the "base coat -clear coat" Highland Green metalic paint on the 2008 and later Bullit Mustangs match the Hue of the 1967/68 Mustangs Highland Green Metalic, which was an acrylic enamel. The new paint looks just like the original, a little more glossy, but the hue is spot on.
Again, you did a fantastic job on your Bullit Mustang. Are you going to do the Charger?
