Yeah, Stoner's stands by their products very well. They offered to buy me a new grille. Just take a look at my sticky "Product warning/suggestion." I enjoy using both products as well prior to using the wax/grease remover wipedown to make a dirty window clean. But, please keep in mind that most of these glass cleaners strip off WAX. This means poor visibility in rain. I learned this the hard way. My glass was dirty so I cleaned it with Sprayaway. I drove it around a few minutes after, it started to rain, and I got virturally no beading.
