Airbrushing

I am just beginning to learn taxidermy and only doing whitetail deer at this point. I was interested in getting an airbrush, but am unsure as to what type and brand. Also, I am looking at using the waterbased paints since i am working in my basement and am unsure as to what kind of paints and what colors are the ones to use. I am looking at the Paasche single action aribrush and the polytranspar paints. Is this a good start? If so, do i need a sealer or some type of sealer in addition to the paint itself. I would apprectiate any help and information since I know nothing about airbrushing and the uses. Thanks.
