Really, all those I gave away and no feedback?! Lesson learned...well, for those that are interested, it is similar to Rainx as far as the results, only it lasts for several months. Same stuff the Navy uses on Jet windshields. Good luck finding it though. I bought a whole box when I found it, they go for around 5-10 dollars an application. Really nice in the winter, you just hit the ice, and it shatters right off.
