AMMO by MIG Accessories - Masking for Modelling

Item: Airbrush Stencils

From the Manufacturer:

These photo-etched stencils will allow you to accurately depict worn and discolored surfaces easily and represent repainted areas easily by simply placing the sheet over the desired surface and then spraying the color with the airbrush using low air pressure. You can also achieve soft-edge patches by slightly separating the stencil from the surface of the model to paint mottled camouflage patterns. There are three sizes used for different scales and finishing options. After each use, always clean the paint from the stencil carefully with Cleaner A.MIG-2001.
