Liquitex Slow Dri Blending Fluid

This clear-drying Blending Fluid is uniquely formulated for superior surface blending with acrylics. Add up to 50% of this medium without jeopardizing the strength of the paint. It increases the "open" working time up to 40%. Great for forming softer edges and modeled forms. It dries clear, and is flexible, non-yellowing, and water-resistant when dry.
