I have used the HF guns to shoot epoxy & hi build primer, but I never tried them with paint. It did a pretty nice job with the epoxy. But I have a 7.5 HP 80 gal tank.
FYI, if you know someone who has another compressor that you can borrow, you can plumb them both into one line and double your air delivery that way. I saw a guy on You Tube who had 3 small compressors running at the same time to paint his car!
