Yeah, that's what I use also. You can get it at any Pep Boys for about $3.00 a can. I'm sure you can find it at any hardware store.
I use it as a preventative measure for my windows. I went to Moab this past year and noticed my windows were barely rolling up because of all the dust. I forgot to bring the spray with me to Moab, but it was the first thing I did when I got home.
Peace.
