A semi-matte, quick-drying medium, Winsor & Newton Liquin Oleopasto has a soft gel consistency with some brush drag, ideal for leveling crisp brushmarks and providing bulk in impasto and texture work. When added to paint, Liquin Oleopasto extends tube color. When dry, it retains knife and brushstrokes and won't level out. It dries to a crack-resistant, virtually non-yellowing film.
