I’m spraying epoxy primer using a 1.4 tip and various inlet pressures from 20 -30 psi, but seems no matter what I can get it to spray out smooth like a paint would. It appears to spray out in droplets leaving a pebble like finish. It’s not a real big problem since I’ll be sanding it (with 220 or 320) before spraying the 2k primer. It would be a lot less work if I could get it to layout smoother. The gun is clean and all the air passages are clear. Any Thoughts?
