Air Supply You won’t get very far at all if you want to paint your car at home without an air compressor, and for this job Harbor Freight supplied one of their new 2hp, 29-gallon, 150-psi compressors. It delivers 5.9 cfm at 90 psi and 7.3 cfm at 40 psi, and features dual pressure gauges and a built-in quick coupler. It operates on 120 V and 15 amps, and while not huge, capably handled this paintjob, though admittedly it does struggle to keep up with a DA sander for long periods of time, but then a DA sander does require an awful lot of compressed air! Overall, this is an ideal compressor for home use, and is way more affordable than a two-stage compressor, capable of handling anything a hobbyist should require. It’s also easily portable, meaning it can be moved outside the garage during painting.
