I got an 82 cutlass supreme, 2 tone brown, interior is perfect except the door panels are easily scratched off with a fingernail and by the back windows also. A friend that does custom interiors told me to take them off and sand down the panels and repaint them. But is there like a different type of material i should use or should i just repaint them like he said? The rest of the interior is brown cloth. So any suggestions would help.
