OK, your post above actually released a major brain fart I suffered during this experiment. When I did my testing, it was with my RG-6 and not the LPH-80 that destroyed my artwork. You might be able to spray that stuff with the LPH, but I can't. But what I did re-discover was that the RG-6 is what allowed me to maintain control and not let the 4004 orange peel on me. I have no idea why I completely forgot that. I am able to spray AG-2050 through my LPH-80 and it lays down pretty good But it is way more expensive than the 4004.
