Review on McKees 37 MK37 515 Performance Fluid_Ounces by Michael Hogate

I used this on the glass of my 23 year old car. There were water stains on the windows that I couldn't remove with either glass cleaner or clay. I applied this to a microfiber pad and hand rubbed the windows with moderate pressure. This material removed 85-90 percent of the water stains and I'm sure if I had used a buffer with a glass polishing pad I would have removed them all. This is great stuff.
