"Water just runs off clean glass much as with the Rain-X."
Rain-X appears to increase the surface tension or something as 'contact angle' is greatly increased, resulting in beading instead of wetting. We use to check for cleanliness on some surfaces by monitoring the lack of beading.
I like RainX a lot, and find that in some rain the wipers just can't keep up, while with RainX I can often stay on low speed.
