Masking Fluid Marker Pen, watercolor

Masking Fluid allows you to protect or highlight areas of your work when painting with watercolors. If you prefer your masking fluid thinner, you can thin it with plain or soapy water before applying it. Wait for masking fluid to dry completely before painting around the dried fluid. This masking fluid is an easy to see blue color when wet and dry. You can remove the dried masking fluid with a soft eraser or a rubber pick-up.
