Ok here’s the deal fellas, I have what seems to be a custom interior job in my 81 Jimmy. My seats are doeskin as are my rear panels and carpet. My dash front door panels and headliner are dark brown. The door panels were painted the brown color once before. I got a new Dark Brown Dash and now wish to paint the door panels the same color. What every the person used before me did a good job as it look clean and profession. Now the question? Since the front door panels are hard plastic should I use paint or dye to change their color? In addition what should I use to prep the door panels before painting/dyeing them so the job sticks?
