GOLDEN Soft Gel Medium, Gloss, 8 oz. jar. Soft gels are moderately pourable, hold only slight peaks, and are ideal for glazing and other techniques that require transparency. Soft Gel Gloss, thinned with water at a 2:1 ratio, can also be used to create an isolation coat over acrylic paintings to seal the surface, lower the absorbency of the surface and more. GOLDEN mediums and additives provide infinite control with acrylic colors. Mediums control transparency, viscosity and surface sheen, while additives control paint’s working properties.
