Liquid Mask is used to reserve areas
which are to remain unpainted, especially in airbrush techniques. The
product forms a protective film on the area which the artists does not
want to paint. Once the work is dry, liquid mask is rubbed off revealing
the unpainted area. Use with brush. Shake lightly and test on surface
before use. Do not leave applied for a long time. To remove, peel or rub
carefully once dry. Keep from freezing.
