I'm getting ready to try my luck at painting with HVLP. My last effort at painting was an 15 tears ago with a Binks Model 7 suction cup gun with a 3Hp,22 gallon compressor. I'm looking at getting a DeVibliss Finishline 4 gun, which requires 13CFM@23 PSI. I'm trying to keep the compressor under $1K, and see an Industrial Air 80 gallon single stage on Amazon, which will do 14CFM@90,16.1CFM@40 PSI or a Harbor Freight 60 Gallon 2 stage, which will do 15.8 CFM @ 90 PSI, 16.4 CFM @ 40 PSI. I'm not seeing an 80 gallon, 2 stage in my budget. So for painting a whole car at once, is the 80 gallon more important than the # of stages? The Harbor Freight compressor is $150 cheaper, and seems to have great reviews, with the pump being from Italy, tank from USA, and motor from either USA or Mexico. Any opinions or lessons learned?
