WaterBorne ™ Slo-Dri (retarding fluid), 1/4 oz dropper bottle
Use this additive with WaterBorne BASIC and PreBlended colors to extend drying time. It increases transparency when blending and washing colors. It helps to reduce paint forming a skin on the palette.  Cleans up with soap and water.  (The product you'll receive is crystal clear, not cloudy as the photo shows)   Too much SloDri can cause adhesion problems with your paint layers.  I recommend you use not more than 10% to 50% SloDri to paint.
