Permanent Masking Medium —

A non-removable, transparent liquid mask, this medium is excellent for detail. It can be applied directly onto the paper, or mixed first with watercolors. Ensure that the fluid is thoroughly dry before overpainting. Wash brushes in warm, soapy water before using other colors.
