Rain-X has a new application system out. It is like a bar of soap or deodorant so it is easier to apply then the spray, which I always put on uneven, and ended up with streaks. The new system also has a buffing towel to finish the application, so it is a lot easier to use. The new system is a breeze to apply compared to the old. Rain-X has been around for years many race car drivers use Rain-X instead of wipers and they seem to have no problems. Before applying Rain-X be certain you have a clean windshield. I use bon-ami it does a super job and there is no fear of scratching as with many other products. While you are at check the wipers and washer system we are not that far from sloppy roads
