I bought this stuff a few years ago at the Auto Show - it doesn't have a name, but it works amazingly well. It comes in a clear container shaped like a prescription bottle, and contains 3 pink sticks. You literally draw a big "X" or a series of "X's" on the surface that you want to anti-fog. You then wipe it with a clean cotton cloth or a Viva paper towel until the glass is clear. Each application will work for about 3 days or so, maybe a little less if there is a lot of humidity. I'll take a picture of it, and post it - there might even be a phone number or web address on the container. I bought it a few years ago, but my car windows don't fog too much, I mostly use it for my glasses which fog up when I get out of the air conditioned car. One stick lasts more than a year when you only use it for eyeglasses.
