1969 Dodge Dart Swinger 340 Sold at Mecum today for $40,000

Basecoat / clearcoat most likely . I have the twin to that car but chose to go white top and interior. And mine is a factory painted top car .
I also used a single stage paint because it looks deeper and less surface shine .
I think all these older cars look much better in single stage. They have a "fake" look about them in base/clear, IMO.
