Woody,I spray lacquer,I am a woodworker, and my gun sprays @28.5 psi. I pull the trigger half way and get just air no finish and then I adjust my pressure to 28.5.
Also I am very interested in your thread about enamel. I just sprayed Tractor Supply tractor paint on my snow blower.
Looks good but then I am not getting fussy about this unit.
