My dad bought me a Pasche Raptor airbrush for my birthday.
He doesn't know much about airbrushes, so he basically went online and bought the one with the most features he could find, so it's a Double Action, Internal Mix Gravity Feed Airbrush. He clearly made a good choice, it looks like a very fancy airbrush.
But, my previous brush is a bare-bones, single action siphon feed Badger 200NH. I really don't know much at all about the differences between the two types. What do I need to know?
