I bought a Harbor Freight's HVLP Spray Gun and I was figuring out how it works today (I've never painted a car with an air sprayer) so when I hooked it up to the air compressor, the air control knob continually leaked air. It didn't matter if I turned it clockwise or counter-clockwise, it was leaking. Is the gun flawed?
Another problem I am having is that there was very little air being shot through the nozzle. So, I'm not sure why the control knob was leaking, but is the reason why there was very little air passing through is because I have a 30 gallon air compressor?
