You mean the UDF (upper door frame) color that is on the doors of the car? If they are coded black (should be on your fender tag) that is exterior gloss enamel.....same stuff they would paint the car with. The UDF color was applied before the body color then masked off. The attached is a pic of the original black off of my Daytona. The Chargers had a pad covering the UDF so it wasn't painted there...A Bee, Runner etc. would be.
