Many years ago one of my neighbors related a story about how,
during the depression, she and her husband manufactured a very shiny
black durable paint and sold it for painting automobiles.  As I recall,
they used a product called "Gilsonite" and mixed it with gasoline.

 [ Found at http://en.wikipedia.org/wiki/Gilsonite :
 [
 [   Gilsonite(tm) is a brand name of a natural asphalt mineral called
 [   uintaite or uintahite.  It was used by Ford Motor Company as
 [   a principal component of the Japan Black [paint] used on most of
 [   the Ford Model T cars.
 [
 [ Henry Ford painted cars with it because it dried quickly, especially
 [ when thinned with benzene or gasoline.  True lacquer finishes need
 [ several days.  More at http://zieglerchemical.com/gilsonit.htm
