airbrush is the smallest type of air operated paint sprayer available.
Airbrushes are commonly used for painting very small components,
or, in the hands of a highly skilled user, they can be used to create
highly detailed works of art on a vehicle's bodywork.
An airbrush works by passing a stream of compressed air through
a venturi, which creates a suction force that allows paint to be
pulled up from a connected reservoir. The high speed of the air
atomizes the paint into very tiny droplets as it blows past a very
fine paint-metering component. The paint is then propelled onto
the surface which is being painted.
