Stoner is a classic brand found in most garages, and for good reason. I'm sure you've used plenty of Stoner products before, from Invisible Glass to their various cleaning tools for you windshield and rear window. Michele and my mother have been using this stuff for the house windows forever and it eventually crossed my mind I should try it on the vehicles. Since then, I've begun using Tarminator and Invisible Glass regularly, in addition to their Reach & Clean tool.
