Wash and dry the jar to make sure there is no dirt or residue on the surface. Put on the rubber gloves and remove the lid from the jar.
Drop some paint inside the jar and twirl it around until the inside of the jar is completely coated with paint. Let the jar dry completely (you can turn the jar upside down to speed up the drying process). Recommended drying time is overnight.
