Rain - X has always worked for me in the past, but.... Lately, no matter how I use it, warm or cool temps, warm or cool windshield, leaving it on for a short or long time before buffing, I still get a film left that takes so much elbow grease to remove, I have now given up. does Rain - X get old? Should i switch to something else? Any ideas would be welcome.
