Winsor & Newton Griffin Alkyd Fast-Drying Oil Paint, 37ml, Permanent Sap Green. Traditional oils, wonderful as they are, take a very long time to dry. Griffin Alkyd paint dries much more quickly, meaning that impasto and glazing techniques can be done in a single session. This color offers an easy buttery flow and exhibits consistent drying times with minimal yellowing and more brilliance than traditional oils. It is generally workable for 4 to 6 hours and dries in 18 to 24 hours.
