Glass Shield Windshield Rain Repellent Coating with Cleaner - Auto Detailing Kit - Repels Rain, Sleet, Snow, Bugs - 3 pack

These worked very well for me! I had hard water spots on my truck windows, and glass renew was able to remove all of it. I would recommend.

Works really good, the renew cleared up my hard water spot on my glass. The water repellent works as good as Rainx

Not sure whether it did anything. For some time definitely I've got some stubborn soapy windshield after each rinsing while driving.

Just Ok. The cleaner for the water spots did absolutely nothing! Are used it four times on a glass shower door and did not see any improvement in the hard water spots. Previously I had tried other products which also did not work so I was hopeful with this one. The repellenabd in cleaner are no better than RainX which I could have gotten for less.
