I have noticed a film when I use the wiper blades. But, after about 10 minutes or so when the windshield gets warm, it goes away.Originally posted by Don:
I'm surprised no one else has had the RainX buildup on the windshield. It causes the blades to skitter and there is a foggy film after the blade wipes off the rain. It's most visible at night when there is a light shining on it, like a street light.
