Daniel Smith Masking fluid provides excellent coverage and an easy flow for brush application, or you can apply it straight from the bottle. Its off-white color dries to a transparent caramel color. When left on a painting for as long as over a month, this masking fluid still peals cleanly and easily from all watercolor surfaces with rubber cement pick-up. This package includes five fine-point tips that attach to the bottle as a drawing tool for fine lines, dots, detail outlining, and highlights. The tips can be trimmed to various thicknesses to achieve the desired flow amount.
