As you can see in the demo video, Ultra Ever Dry works to prevent not just water from soaking into a treated surface. It apparently works on pretty much every liquid or near-liquid substance and in effect goes beyond being non-stick to create a near-frictionless surface.
Unfortunately it only works on liquids, so you can't spray the bottom of your shoes and slide around. The coating on a treated surface can also be scuffed or otherwise scraped away. This chemical also requires some serious safety equipment while being applied. You're not even supposed to get the uncured Ultra Ever Dry on your skin, and that's probably going to limit its uses almost as much as the high prices ($160 for a qt of top coat and bottom coat).
Still, I'd like to coat my car with this stuff. And I would, if not for the fact that it's only available as a milky white. There's no formulation of Ultra Ever Dry that dries clear, so you kinda can't put it on a window or anything you need to see through. And yes, that does kill any chance of using it on an ereader or tablet, alas, unless you want to read the screen through a white film.
But who knows, maybe the engineers who developed it are working on a clear option. It would certainly have market appeal. I would love to spray this on a tablet and them use Takara Tomy's screen cleaning robot to get rid of fingerprints and smudges (I am a firm believer in over-engineering a solution to nonexistent problems).
