By the end of the day the continuing chemical changes will have caused the gel to set up and become more difficult to work with. Once you stop brushing it, it sets up to hold every detail in the brushstroke. No matter how thick you paint the strokes, they won't sag and run. The lubricating qualities of Maroger's Medium give you paint handling you simply cannot get with standard painting mediums. As if that weren't enough, because of the dissolved lead salts in the Black Oil, Maroger's Medium speeds up the drying of all oil paints.
Most colors are ready to be overpainted in a matter of hours .
We get the best of both worlds by mixing Oil of Clove into the paint on our palette. That retards the drying allowing us to keep a full palette without having the scrap lots of expensive paint due to drying out. The Maroger's Medium accelerates the drying while the paint on the palette stays moist and usable. It's definitely the best of both worlds. Maroger's Medium is not megilp.
