This stuff, if it doesn't cost an arm and a leg, looks like it could totally revolutionize they way we live. It's superhydrophobic, meaning it repels water VERY well. It can be sprayed on clothing, shoes, and just about anything you don't want to get wet, and water and oils and anything else wet will run off without getting it wet. I want some... SOON!
I want to coat my truck in it, take it mudding and drive away clean
Here is their website for more information about it.
