I've got a problem with the side windows that is bugging the heck out of me. I put in some washer fluid that appears to have an additive that makes the water bead up as good as Rain-x on the windshield, but it has managed to drain onto the front half of my side windows and has smeared them up really bad :( The windshield is clear, whereas Rain-x became smeared with the windshield wipers, but this is from the windows going up and down and managing to make it very difficult to see with them up. Help :bb
