You can color sand the orange peel out and buff. Seems you are not atomizing the paint properly. Try widening the fan and/or closing down the material control slightly.
Remember, HVLP means HIGH volume. If you dont get the spray pattern right, you end up with large droplets of paint that have a lot of solvent in them....orange peel. If you change the fan control, you must then re-adjust the volume control and check your spray pattern. The wider the fan, the more it breaks up the droplets. When checking spray pattern, look for cigar shape that is solid in the middle and (progessive)smaller dots around edges. Pull trigger wide open as fast as you can and release at painting distance to check spray pattern.
30 psi at gun inlet is proper. You can adjust slightly to help with atomization, but I find I can get what I need with fan and volume control. Practice on scrap metal before shooting your finished product (each and every time).
Oh eay, I am not an expert either, just a hobbiest, so take it for what it is worth.
