"Treatment makes surfaces self-cleaning"

I read this article, a few weeks ago

Do anyone know more about this? Can it actually be applied to metal?

i.e. car body, so I won't have to wash my car ever again:!) , I'm just kidding, but wouldn't that be great.

Actually that fenomena use hydrophylic characteristic of material. One material that exhibit that characteristics is titania. Water form a layer instead of droplet on a hydrophylic surface so the dust stuck in water layer and easily removed by water.
I think we can use in metal, just coat it with titania.
