I have a can of paint that I bought probably 2 years ago (oh man, I can't believe it has been that long) that I never used.. You think it is still usable? If it is I am going to take it back to Lowe's and have them shake it back up for me. I've read different things online about the "shelf life" of paint and I got different answers. Anyone used paint after having it a while? I'm not going to use it on my walls, more than likely a project so it's not like I am going to mess up anything major with it.
