Sagola is good but face, I have Ja -fe or Ga-he, (it is the same brand), gravity, 1'20 peak and does not go wrong, for the moment to paint some things, some mirror, and others works quite well, the air I have 2.5 bars with paint to the solvent and 3 with water paint.
Practice painting things that do not need a perfect finish, compressors, machines ... and then you will be looking for finer things, consoles of the instrument box, mirrors, bumpers ...
and be careful with the dust of the street or where you paint that it sticks in the pieces when the paint is fresh and is a whore.
All the best.
