What’s the difference between HVLP and a regular pneumatic spray gun off an air compressor…. like for automotive?

Pure HVLP uses a turbine for it’s air supply and runs at high volume but low pressure air.

An HVLP conversion gun runs on a “normal” air compressor, but you need to reduce the pressure and use hose large enough to provide adequate volume. You also need a compressor tank with enough vilume to spray for a while without waiting for the tank to recharge.

HVLP is the modification for the air spray gun. He uses the “high volume” air pressure to do the atomization. The air pressure is kept in the low pressure to increase the efficiency of material transfer.
It is rather limited to work with material with low viscosity, but it works well for most of finishing material for wood finishing.
