Hello everyone. I am finally getting to a point of doing a little paint work on my truck. I just bought a sharpe HVLP gun and have a question. I have a little air pressure guage on it @ the air fitting to the gun. They reccomend I believe 40 to 50 psi @ the tip. Is that # that it should be when you are pulling the trigger or when there is no air flowing. I set it @ abou 50 on the guage but, when I pull the trigger it drops to about 20 . Thanks in advance...Dave
