I am redoing the interior on my 66 black. The rear part of the dash is supposed to be 60% gloss correct? Should the door tops, rear of seat and skirts and the console be paint 60% gloss as well? Paint on the exterior is almost complete and things are starting to go back together so I am begining to believe that there may be light at the end of the tunnel after all.
Dash is actually two shades of black. The Upper dash is flat black (or 0% gloss). You don't want any gloss to reflect sunlight in your face. A lot of us have used SEM's trim black here. Works well & looks close to factory.
The lower dash is glossier than most people think. Your results will depend on the type of paint you choose. If you want it to look exactly like the factory did it, you'll need to spray it in lacquer. Dupont code 88L or PPG code 9248. After a day or two, you'll need to color sand & buff it. Lacquer sprays flat & needs to be buffed in order to achieve proper gloss. The factory baked these parts, so us home restorers have to do the next best thing.
If you can't get lacquer where you are, take those codes to your auto paint store & have them convert it to a single stage urethane. From there you'll need to experiment on your desired gloss. I'm not sure how this shade of black will lay down straight from the gun.
Door tops & steering column should match the lower dash identically.
If you use the lacquer on the seat backs & console, just leave them as is out of the gun. No need to sand or buff them.
