I have been doing painting around the house. Ran out of the new oil based paint I had purchased recently and remembered I had an old can of Sherwin Williams of the same color. Can is most likely 18 years old. Used a mixer on the electric drill as everything had settled out. Seemed to mix up just fine. Painted the inside of the garage exterior door with it. Seemed a little thick, but spread ok. Have been waiting days now for it to dry out and it is still tacky. It is green....(hunter green) Just not JD green, although the wife was thinking I was going to paint it that. Any suggestions?
