Yeh I'll try that next. I just did a German Camo Black Brown on a pegasus and started from 2 drops and 2 again when it was all watery.  Another two cause it was still watery.  Then another 2 and it started doing that thing with the black again.

I wonder if it's the airbrush?  (I dunno why though) When I did the first test when I got the paints from you it was spraying nice and it was through my Anthem.
