Sometimes when I've got slightly misty results from AP, I've found that it's actually sort of dry, half-loose residue and can be removed with water and gentle sweeping with a big brush. Just watch out that you don't ruin any water-sensitive basing effects. Other very mild dilutants could possibly be tried, but those come with very obvious risks. If water or the strongest you dare to try don't work, maybe it's time for a new gloss layer as plan C.
I've been happy with AP but my preference for "right" look may be a bit different because most of my current projects are supposed to look dull...
