Incredible White Mask Liquid Frisket 4.5 oz. This is a wonderful masking fluid, it doesn't build up in your brush as fast as some products. It dries clear so you can see through the masking at either paper or your base color. You can also use a hair dryer and it will still lift off with a 'rubber cement pick-up'. Dampen your brush in clean water; brush onto a bar of soap, liquid soap, or hand soap; lightly blot off on a paper towel; then into the Incredible White Mask. Do not allow the masking to build up on your brush. Frequently wash your brush out in your water, then repeat the steps.
