Also I take a small can of por-15 and punch a hole in the center of the top and seal it with a #12 sheetmetal screw. When I need to paint something I just remove the screw and drip some out. The curved outside bottom of a beer can works great.. I then reseal it with the screw and put in my shop fridge.. one can last a long, long time. Remember.. a little goes a long way.
