Many motorists have encountered the problem of windshield wiper contamination. It looks something like this: during the movement of the wipers, a trace in the form of water or oil streaks is left on the glass, which disappear a few seconds later. As a result of using water or oil-removing agents during the cleaning process, streaks appear after a while, interfere with the paintwork and make the glass "pop".

And of course, the film that had been on the glass did not freeze, but the thawing of the glass as a result of using this method, a thick layer was formed. In another headlight, I tried a new one, the usual Russian roulette wheels in black and white. In the end, I decided to make a hybrid glass with Russian film-Glas. The experiment in the field So, one headlight is put on, and the other two are put on in the same spot. Headlight A ist coat, glass cleaner and cotton wool. The headlight B is used instead of the usual racing white tape that is used in Russian traffic. The main thing is not to change the fogging – white tape always sticks tightly. The headlight C – it worked even better the second I started painting it. It glittered like a Christmas tree. And the third headlight, which is also on the fuse box, which is connected to the street light, did not freeze even when it warmed up under the sun. It was
