I've seen this stuff advertised for years in all kinds of car mags, and never tried it. But alas, my beater miata's windshield was disgusting inside and out. I had tried windex, vinegar, and my personal go to favorite the LA's totally awesome cleaner they sell at dollar general, nothing could get the film off of the windshield. Buy a can, 3 applications later and it really is invisible, except for all the micro-chips in it. I've now cleaned every window in both my cars, the bedroom tv screen, and all the windows I can get to in my 2nd story apartment.
Awesome product! Highly recommend.
