Hey Muskin i am a painter and you have to thin the paint so that you dont get orange peel. I am very experienced with HVLP and various sprayers and you shouldnt get orange peel anyway if you spray but dont spray on heavy and i do know that if you are going to spray you have to thin and it eliminates the orange peel.Thin maybe 30% with orderless mineral spirits (cuts down on the smell)that is good enough to go through an HVLP hope this helps
