That's pretty much all rain-x is anyway, right? A form of wax designed specifically for windows.
I need that fog-x, though. When I'm at work, no matter the season my windows get all fogged on the inside. I can't stand it because I can't see anything and I have to wait like 5 minutes until my heat actually gets warm.
