I'll be spraying this stuff on my riding jackets and boots, (but not the soles, obviously). Watch the video at the link... absolutely amazing.

Edit: They've changed up the videos. The imbedded one is now the Rust-o-leum advertisement. Click the link just below the picture of the pair of canvas shoes for a six minute video about the product development and much more amazing demonstrations on cloth and cardboard surfaces.

Interesting. The simple principle that they mention 'high angle of contact' with water makes it sound like the mechanism depends a lot on the geometry of the surface that it creates. If that's true then I wonder how well it holds up to constantly being pressed on or rubbed (like as a surface treatment on clothing or footwear). No doubt they've spent time trying make something that's usable. It'll be interesting to try it out.

(edit: if the 'high angles' mentioned are built at the molecular level, then obviously there's no surface to wear off except for the stuff itself ! duh..)
