Well said Toolsman, and thanks for the kind words.
I would like to add how important it is to know what air
requirements your gun choice needs. You probably want to make your
choice by how much air your compressor delivers.
Most compressors mfg's stretch on their output cfm specs and most
spray guns spray better by upping the psi, which takes more cfm.
So give yourself a little room for air requirements and supply.
You also don't want to be so closely matched that your compressor
runs most of the time, that builds heat and creates a lot of
The HVLP's do require a lot of air, usually around 10 cfm.
Some much higher.
But a conventionl gun can use a lot less and spray really well,\
I find the HVLP's need the psi they suggest, sometimes more, but
the conventional guns can spray at a lot less psi and still give a
good finish, meaning a lot less CFM.
Here's one I've sprayed lacquer with unbelievably well.
Spraying at 30 to 35 psi this gun uses less than 4 cfm, it's a great
choice for a small compressor.
I sprayed some pretty slick cars with this gun and a
3/4 hp compressor.
