Try to find a paint store that sells paint for school buses. They mix it 50 / 50. That is what I have on my Dart , it looks real good.Start with a very light or it will run.
FYI, you have to ask for DCC 9355 now. (The old stuff was lacquer). Just bought some last week for my hood. Cost about $100 for paint (pint), reducer, and hardener.
I've also been using Sikkens Autocryl "Rally Black" for some interior stuff. It's a nice semi-gloss black.
