HVLP?

Whats the compressor rating for a HVLP gun to do serious work? I see the HF turbine HVLP gun. looks like a Wagner power painter with a vacuum hose on it. Does that even work? Its just that its included turbine compressor would save you some coin if you didn't have a 30 gallon 12CFM compressor. I already have a HF gun and a 20 gallon Craftsman compressor, maybe 6 CFM?

Don't buy that Harbor Freight turbine thing. I did, used it just fine for one project, and midway through project 2 it literally caught fire.

HVLP guns want a lot of air. My Devilbiss calls for 12 - 15 cfm. My 5hp Craftsman compressor can't keep up.
