<strong class='bbc'>Does 20/20 [by design] leave behind some type of water-repelling film? A few users said something like this but I have not found anything on bottles of 20 / 20 that mentions this. Was I thinking of a different glass cleaner? [/b]</blockquote>
I don't know if the water repelling effect is intentional, but I can tell you 20/20 definately does make the water bead up and roll off nearly as well as Rain X does without the nasty film. I've been using 20/20 in my detailing business since it came out and have found it is also excellent for removing the new car haze on the interior windows, too.
BTW, one of my customers mentioned to me that whenever it rains after I have detailed his car, he noticed the water would roll off his windows just like if I had applied Rain X and asked what I used so he can do the same when he washes his car in between details, so I told him all I did was clean the windows with 20/20.
