Hello, I wanted to open a thread here, where all their experiences with glass seals gather together. There are tens of different manufacturers that offer something like this. Maybe this crystallizes out a product especially (in the positive as well as in the negative area). So I want to start out then, I looked QVC for the first time from a long time (you know, this shopping station ). There they showed then Rain X, I got the stuff somehow and because it all looked so nice on TV, I got around and then spend the then still 30 DM for Rain X. However, the stuff does not really work as great as on TV. First of all the whole light is aired what night of incoming vehicles is broken in the disk and everything blinds, very nice . Since I also drive quite a lot in city traffic, I also had to use the windscreen wiper often, since Rain X is only from 60 km/h The windshield wiper works like lubricating gel paper on this layer and the glare effect is getting more and more cruel. Since then, I have never used Rain X again and was happy when it was down again. Conclusion: If it goes faster on the highway, it actually works the way you hope it will. However, the effect decreases relatively quickly again and the glare effect is quite high. For people who drive almost exclusively highway, Rain X is actually too em if you miss, who drives a lot of Stat, should definitely do without the stuff. And now post your experience
