This masking fluid features an easy-to-use application system, but can also be applied with a brush. The fluid creates an impervious barrier to protect and preserve white areas of paper by blocking washes from flowing into unwanted areas. It applies off-white, dries to a transparent caramel color for visibility during painting and leaves crisp, clean edges when removed. Details:30 ml (1 fl. oz.) bottleIncludes 5 fine-point applicator tips
