I really appreciate the Rain X in a light drizzle or mist, when the water seems to disperse by itself with minimal windshield wiper use. When you apply before the cold weather, though, it helps prevent ice from sticking to your windshield, which is just great. I also like to use the product on the back window, which doesn't have a wiper, because it keeps the window clearer. Follow the directions--let it dry to a light haze and wipe it off with a microfiber or paper towel until the windshield is clear. I'm sure you'll like it.
