I was driving one dark moonless rainy night on a freeway I had to pull over to the next town because I could not see because of the wiper glare from the incoming headlights, I almost hit a tree! I had to go to a gas station and buy some degreaser and wipe off the wax of what ever was on it off the windshield. Sense then I never used anything on the windshields. I think it’s just to much of a liability. Because now when I drive I demand 100% visibility all the time for safety. When its raining the wipers should have "no glare" the windshield glass should be “crisp� clean & clear when the wiper passes. RainX does leave a momentarily glare or bur from the wipers that’s ok for city driving but for a dark moonless rainy night on mountain freeway driving that is not 100% safe. Wax/sealer VM, AIO on a windshield would be even worse.
If you can’t see what’s in front of you for one second its one second less to respond to a situation in front of you while driving.
