Jack Richeson 3-3/4-Ounce Liquid Masque
Liquid Masque is a latex based liquid that dries quickly to block out areas of your artwork that you do not wish to cover in paint. Simply apply with an old brush, let dry, paint around, and finally rub masque away with an eraser revealing a white or unpainted area. Masque is tinted light pink to enable you to see the masqued area.
