Mixed with oil paint, Art Spectrum No.3 Medium is thicker, oilier and slower drying than Art Spectrum No.1 and No.2 Mediums and can be used as the final medium in the 'fat over lean' oil painting sequence (made easy using the Art Spectrum range of oil painting mediums). Art Spectrum No.3 Medium on its own can also be used as a general oil painting medium and leveling agent.
