Slowdry Medium improves flow while slowing an oil color's drying time. This medium will produce a high gloss finish and is a great match for wet-in-wet painting techniques. As with Matte Medium, simply add this medium to paints in small amounts to find the ideal, desired result.

Available in a 2.5 oz. bottle
