My windshield had scratches use of over 200 0000 km away. At the "rub" the wipers at the point I had, at oncoming vehicles, light reflections over the entire surface.
Started to polish my orbit sander (about 120 Euro class Bosch) and a present polishing pad made of foam ... Result: absolutely no improvement discernible on my windshield.
So from a polishing pad made of felt (original accessories) purchased at the hardware store ... slightly moistened with a lot of strength about 45 min (pressure) and full speed polished. Temperature when working about 6 degrees Celsius, no dry product's information notices. It consumes about half the bottle.
Result: The disc has a refractive almost like a new one am really excited and now again more safely.
Tactile scratch (from careless scraping ice) are not removed / is not claimed by Sonax.
