I need a compressor to run HVLP guns, as used for automotive painting.

It does belong here, as I want to do an automotive finish on my woodwork projects.

Any way, what compressors would you suggest, with adequate CFM, PSI, and gallon for running an HVLP gun properly?

I am especially interested in one I can get at lowes, but if not - that's fine.

Thanks!!

Edit:
To give an idea, this HVLP gun needs 12 SCFM @ 45 PSI.

This compressor only provides 2.2 @ 40 PSI.

Not sure as to what is available in the US but if I could suggest, as a general rule - get the biggest you can afford or fit into your workshop - it pays in the long run especially as, when you have one it tends to generate solutions to all sorts of problems which arise in the shed - it's a little bit like the saying "You can't have enough clamps" - "You can't have enough capacity or air flow". :U

If I get one with a large gallon volume, does that mean I don't need the SCFM the HVLP gun requires?

I only need equal SCFM if I'm doing a "large" project, so the compress doesn't run out of air and have to recharge - right?

In other words, if I get 60gal and my project takes 20gal, the SCFM is irrelevant - as long as PSI is high enough. Right?

The gun requirements will remain the same irrespective of the compressor size.

Larger capacity means that the compressor cycles less and gives you a more stable airflow - it also allows you to use more air tools and nail guns if you wish.
