Tech Nova I understand and I'm just trying to figure this out. I have 3 HVLP guns and they are all cheap. 1 is the purple gun and the other 2 are CARTMAN H-827P. 1.4 TIPS. I also have a new siphon gun and a bunch of old ones. My HVLP guns have 2 holes on each side that are bigger vs the siphon feed guns with one hole that are smaller. And you are right why are the pros painting with them if they suck. I don't get it and thank you for your input. I appreciate it.
