Under carriage/under chassis pics..

I know that 1965 cars has a greenish primer that the car was dipped in before the car had the top coat on. At least on my 65 Dart GT. The strange thing is that on the doors they were dipped about 45 % of the door up. However between the fender and the inner fender was it this greenish primer too!!!!

But I think you should do it the way you want it. Original of just a restoration?
