I have a 69 4 door Coronet and I am planning on painting it the original color which was B3 blue. I like the color personally. Currently the car is more of a B5 blue color on the outside, but under the trunk, hood, engine compartment and in the door jambs it is the B3. If I go back with the original color, this would probably make the paint job easier, but since this is a 4 door, and no one cares about 4 doors, I am toying with other colors. Just looking for opinions, no wrong answers.
