Has anybody used Griot's Garage Glass Sealant? Looks like an interesting alternative to RainX and the like. I'm currently on my last bottle of GLass Science Rain Clear which has been an awesome product; I get an honest year in between applications on my F150! Unfortunately I simply cannot find it for sale anywhere local. Might just pick it up from Autogeek but wouldn't mind giving something new a try as well... so long as its a good product!
