I wouldn't endorse the "no problem" part, myself.
It doesn't matter so much what the type of paint is, but the Aztek isn't as reliable as a good double action airbrush from Paasche, Badger or Iwata, and they all cost about the same.
The Aztek has a design flaw. The needle return spring is in the tip and therefore in the paint path. They gum up pretty quickly with acrylics.
By all means try it and see, but in my own experience I had a lot more confidence and therefore success when I put my Aztek aside and started using my Patriot.
