My 69 mach needs the black parts of the exterior painted. I just bought a nice paint gun and regulator. Whoever painted the wing and hood did a pretty bad job and I would like to try to repaint those parts till I can save up enough $ in a few years to get the whole car redone. What color is it low gloss black? Do I need to primer it? Whats the best way to prep them and paint the black part of the hood? Should I just scuff it up and tape it off and spray it over?
