Learning to paint....

I forgot to add, that I bought an old timey paint shaker at an estate sale. It's a Red Devil brand, and will do gallons and quarts. It is made to do 2 gallon cans at a time, but the clamp on 1 side is missing. It's so old, that I can't find replacement parts....but it will shake the hell outta some paint! Sure beats doing it by hand. Keep an eye on Craigslist, and you will spot one every now and then.
