Review title: Not the best windshield treatment out there.
Product review: Too bad it is not better, since it is simple to use. So, I have tried almost any product out there similar to Clarity Defender. I have tried Rain X, Aquapel, Diamondite and 4 or 5 other products. All of them never lasted as long as a similar product from NanoSafeguard. It is also cheap since I can use it for almost every glass surface of 2 whole cars.
