Hey Mr._Bombero, go to Sears and get a 5hp, either vertical or horizontal, your choice. That way if you decide to use an hvlp gun you'll have enough cfm. Home depot or Lowes are good bets as well, around 250.00 and you're set for a while anyway.Look for one that puts out at least 8-9 cfm. There are hvlp guns available
that don't require more than that. Any less and you'll get a lousy job.Hope this helps
