I am painting a car for my friend and have to paint the inside of the doors and jambs, Should I paint them and the outside of the door or should I paint the inside of the doors and jambs and install the doors and paint them when I paint the car?He says if we paint the outside of the doors we may scuff them up when we install them, But the jambs are painted and inside of the doors so to me the problem is trying not to scuff them. Your thoughts are appreciated.
