I used it when i did my windshield. It cleaned it up a little bit but overall I was not impressed especially using a wool pad on a rotary polisher. If it catches the finger nail at all it didnt make a difference for me.
I have used CarPro Ceriglass and their low progile glass pads.
My neighbor has a 2015 Infiniti with micro scratches from bad wiper blades and on a rupes LHR 15 mark II, I did not notice any improvement.
