Liquid mask is applied to seal off areas of a model before the application of another layer.
Once applied over a layer and allowed to dry, the next layer is applied and also allowed to dry. The liquid mask is then easily peeled off revealing the "saved" layer below (use an eraser or piece of cloth). This technique is often used in airbrush painting or using sprays, but is equally effective with brush painted areas.
Packaged in plastic 85ml screw top bottles.
