We just got our first snow here on Long Island. Last week I waxed my car and applied RainX to the windshield. Today, there was ice on all windows except windshield, and the wiper just took the snow off of the windshield like it was nothing. The wiper on the rear window just slid over the iced up window, and I had to scrape it. Tomorrow I will RainX the rest of the glass. I highly recommend this for the winter. It makes ice non-existent on windows and makes snow removal a breeze.
