I was at the auto store yesterday, getting them to turn off that Check Engine light on the Mercury, (yes, I cleared the trouble), and I thought about Rain-X. I had never used it, but my brother-in-law swears by it, so I picked up a bottle of their Original Glass Treatment. When I got home, I followed the label directions and applied it to the Mercury, the F150, and the Explorer. Great timing, because by daylight we were having a good, old-fashioned downpour.
That stuff is da' bomb! The water flew off the windshield, it was a lot easier to see the road and the other cars in the pre-dawn darkness, and watching the little water droplets run up the windshield was just about as cool as it gets. This stuff has been on the market for years, and if you haven't tried it, you owe it to yourself to give it a go. Follow label directions of course. Rain-X has the PawPaw seal of approval.
