metallic paints

This may be a stupid question, but can you airbrush non-metallizer metallic paints(silver, aluminum, steel, etc…)? If so do I need to do anything different than when I spray with regular enamel paints?

I’ve had no problem using regular MM or Testor enamels in silver, aluminum, etc through my AB. I find that I don’t have to thin them as much as color paint though.
