hvlp question

im looking to purchase a spray gun and compressor to epoxy primer my mustang. i was wondering what a hvlp exactly means? does that kind of gun require a smaller compressor then any other type of gun? im looking for a compressor but was wondering what kind i should get if i plan to paint panel by panel.

HVLP-High Volume Low Pressure, because it is a high volume gun it will require a larger compressor. Usually it takes about 12 to 14 CFM minimum to properly use a HVLP gun and more is better. I know guys will tell you they run their HVLP guns on less than that but I think if they tried them on a bigger compressor they may be surprised. How big is your compressor?

You do not need a HVLP to spray epoxy. They will work, but not required. I cheap, gravity gun will also work just as well. The more important thing to consider is tip size. Normally a 1.3 or 1.4 will work great for you.

Something with an honest HP specification of around 3hp, belt driven and about 12-15cfm at 40psi. Absolutely no direct drive junk.

I've used an HVLP system with it's own hot air supply for about a decade and it works beautifully, it does take some adjustment in techniques from the regular guns, and I've noticed that the paints even have special HVLP mixing instructions on the can. The major reason for the change is an EPA thing...there is less overspray(VOCs) released. The main difference between HVLP and normal guns is that the HVLP sytem presurizes the gun and blows the paint out (High Volume of paint at Low Pressure), regular guns siphon the paint out of the gun...that, of course, creates more VOCs in the air. I find there is less wasted paint as it goes on the vehicle and surrounding areas are easy to clean up. I like the heated air as well since it helps reduce any moisture that may be generated by a compressor. Not all HVLP systems are hot air.
