Hi, I bought some paint for my '77 Caddy that I was planning on putting on with an airbrush.  I have A Badger Anthem, a Badger 360, and a Paasche VL.  I do airbrushed makeup, tattoos and so forth, so I know a lot about painting on PEOPLE, but I know absolutely diddly about painting on cars.  What PSI do I use?  How far away?  Which brush is best?  If I use the VL, I have a choice of #1, 3 or 5 needle and tip.  Any suggestions will be welcomed with open arms.
