Paint guns are similar in shape to regular guns but were designed for paint application. They rely on the atomization process that turns fluid paint into small drops. These drops create a fine mist that escapes the gun via a special nozzle. The mist then colors the intended surface. Paint guns come with their own container and have several knobs, a trigger in addition to an air cap and nozzle. They are also equipped with either a turbine, air compressor or motorized pump depending on their size, type and model.
