What should i look for in a HVLP spray gun?

im going to attempt to paint my own car and wanted something a little better then using spray cans. i saw the duplicor Paint Hop series paint at autozone, which looked like it was higher grade than the spray cans.





anyway, i believe i will need an hvlp gun in order to apply these paints. what should i be looking for in a spray gun? i just need something cheap that will get the job done- i will only be using it this once. i'll spend up to $40, ebay is crawling with these.





do these guns just hook up to any air compressor? my friend has a contractor grade compressor that i can borrow.





how does this gun look:

That gun is decent for a non professional, but I'd steer away from an HVLP. It takes too many coats because it won't throw nearly the amount of paint as an old school $49 gun from Lowes. I'd also stay away from any thing sold at Autozone under the guise of auto paint. Use ebay or another online paint store, or a tractor supply store. They sell durable paint for less than $20 per gallon and it actually looks great if sprayed even by a first timer.





I bought some aluminum paint that took a really long time to dry, but I used regular paint from them for years on race cars and they looked great.
