I think you are mistaken. Invisible glass is a cleaner... it will remove whatever you put on your windshield. It removes grease and grim with relative ease so I don't think rain-x stands a chance. Anyway, I have yet to use my wipers in any kind of wet weather without ever using rain-x... just a very very clean windshield does the trick... squeaky clean, rain doesn't have a chance of sticking.

 

You do what works for you.

 

haha. good one. i'm just saying i think you are wasting an application of rain-x... it's like waxing your car and then claying it... doesn't make sense.
