Just got me a 68 mustang that is mostly redone and I had a question about the interior door. It has begun to rust a bit and the paint has been rubbed off by the window on the door in the interior. I have been told that you sand the door down and repaint it with spray paint. Has anyone else heard this? I have seen some that are painted the color of the exterior but mine is not. It is black and the exterior is red. Any sugestions on how to do this? I am new to this and want to make this car perfect. Thanks, Mike
