the discs are milky / Matt

Hello There,
unfortunately I can not recommend the antifog agent. I use for several years to Regenabweiser of RainX and am more than impressed. Since in my car constantly writing are over when I get home from work, I have tried the medium.
The discs were cleaned with an alcohol-based cleaner and subsequently applied anti-fog as directed and processed. It looked at first at light at dusk very good and the discs no longer fogged.
But the next morning I drove in the dark to work and could not believe my eyes. Once came to meet another car, I was blinded by extreme streak streaks. In daylight you could see, too, is the disc somewhat dull. Ok, disc again cleaning, anti-fogging repeated application and still not better. Connecting sprayed the glass with water and dried with a fresh microfibre cloth. The streaks are now largely gone, and the disk is not even more for Matt it fogs up as the day without anti-fog ...

Conclusion: this product is not recommended because the view is miserable in the dark.

ps the windows fog no longer if you have a window on the car to be 2-3mm.
Thus, the moisture can self-regulate
