Xylol (Xylene) has excellent solvency characteristics and a medium fast evaporations rate. It is the recommended thinner and reducer for hard to thin oil base paints and coatings. 100% pure, Xylol is the preferred thinner for anti-rust paints, porch and floor enamels, and most other synthetic enamel finishes. Paint thinned with Xylol give off flammable vapors during drying. Always follow the coating manufacturer's direction and warnings and be aware of the increased fire hazard when coating large areas. Limit flammable vapors by only using a few ounces of Xylol at a time. Wait until all vapors are gone between uses. Quart metal can.
