I was lucky and found the spray paint at Wal-Mart. It was almost $9.00 a can. It doesn't take that much paint. Make sure that you shank the can well and use short quick shots into your container. I found that the paint is very liquid and would run to the bottom of the container. I would swirl it around to cover where I had missed places.
After the paint has dried for a few minuets I used a spray bottle with white vinegar. I sprayed the inside where there are beads on the sides, then let it dry. This is the long part. I'm an instant gratification kind of gal and this was hard for me. I had to spray several times. For me this was not a one day project. At one point I even ran my hand up and down in the container and it took off some of the paint(that is what I wanted). This is the part you will have to just experiment with to get the look that you want.
