Airbrushing is similar to spray painting using an aerosol can, except that you can control the amount of paint to be applied to the model. The tip of the airbrush emits a fine spray of paint that is adjustable by regulating the air flow. This tool enables you to create all kinds of unique and painting effects, which cannot be reproduced by either spray can painting or brush painting.
The basic components are the airbrush, a paint bottle and an air supply. The air supply is connected to the airbrush by a hose. Compressed gas can is frequently use as the propellant for airbrushing. An airbrush operates by using compressed air to propel the paint out of the bottle and onto your model. The amount of air through the airbrush is control by a trigger button. When you press the button, the air flows through the brush. When you release the button, the air stops.
