Mike and others have it. Not the paint for an airbrush.
You want a great looking model and you economize on on the very part that will be seen the most, the paint. This is the classic penny wise, pound foolish. It would be like getting a 300 watt high quality amp and playing it through a 1969 VW AM radio speaker. You're willing to pay $30, $40, $50 or more for a model (plus all the accessories) then you turn around and buy cheap jack paint.
