Rust-oleum NeverWet

Well, I'm game to be the guinea pig. I ordered up 2 sets. (They didn't have them in stock at my Home Depot.) I've got a few ideas to try it on; places I don't want stuff to stick to, like under the lawn mower deck for example. I'm sure it will wear off, but if I could go a mowing season without chiseling off the caked on grass, that would be nice. I'm also thinking perhaps the inside of my rain gutters that tend to accumulate debris.

So, what would YOU want to see this stuff tested on?

Come up with a suggestion and if I can, I'll try it and report back.
