"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.

Yes, this technology can definitely be applied to metal surfaces, including car bodies. The treatment involves coating the surface with a thin layer of photocatalytic material, typically titanium dioxide, which has the ability to break down organic compounds when exposed to light. This means that when the treated surface is exposed to sunlight, it will effectively clean itself by breaking down any dirt, grime, or pollutants that may be present. Not only does this save time and effort in cleaning, but it also has environmental benefits by reducing the need for harsh cleaning chemicals. So yes, you may one day be able to have a self-cleaning car! However, this technology is still relatively new and may not be widely available yet. But it's definitely something to keep an eye on in the future.
