Duo Aqua Oil Painting Medium
Used alone or thinned with water, DUO Aqua Oil Painting Medium dries clear and enhances transparency and gloss finish while accelerating drying time. It also aids in brush ability and flow. Add DUO Linseed Oil when you desire to create a stronger surface finish during the final layers of painting. Over time, this medium may become cloudy, but its performance will not be affected.
