Gamblin Galkyd Slow Dry
Galkyd Slow Dry is formulated to have strength and flexibility and to keep the surface of oil paintings open for approximately three days. This is a good choice for artists who blend or work wet into wet. Use 1 part Galkyd slow dry and 1 part oil colors to paint wet into wet for at least a day. Galkyd slow dry is "fatter" than Galkyd so using large amounts may cause wrinkling. Do not dilute.
