The door panels on my '77 were awful looking. Now, a few hours and $15 later, they're slightly
less than awful! For those playing at home, I used Plastikote vinyl paint in Dark Red, which was a verrrrry close match for the original color (I didn't paint the area behind the door panel bag). I used 1 1/2 cans at about $5 a can, and a can of Bulldog(?) adhesion promoter from Pep Boys. There's nothing you can do about the tops that disintegrate from the sun, but at least they're a solid red color again.
