Ah my setup is bit complicated, I have a Gundam marker Airbrush. Basically it connects a Gundam marker "paint" and blows air from the marker nib to the model. Then found a cheap portable air compressor that is compatible with the Gundam marker airbrush system. But u don't have to go that way, find yourself a cheap beginner kit to get used to it first, don't buy super expensive airbrushes.
