Paint Stir Stick

For this room we "salvaged" around for paint colors we had laying around both of our houses. As you can imagine there were a ton of colors, my house and my parents house both do not have ANY white walls. The primer used in this room was primer used in my house in the family room two years ago. The primer was separated and needed to be mixed.  Here is my Dad's sales pitch for his solution,"Got paint that needs a good stirring before use, but don't want to wear out your arm with a wood paddle that they give you at the paint store, cut down a cheap plastic hanger, Chuck it up in your drill, start at low speed and whip away, start at the bottom and work up and down, minutes later you're ready to paint, and saved throwing out perfectly good paint wasting money and polluting the environment!"
