How about anodized auto bodys?

Hi,

I'am reading about the Model S' paint beeing too soft now and then. Since the body is alumium however, would anodization be an option? I know it's not trivial, but so is Tesla ;)
Anodization/Elox can provide at least some of the colours in full saturation, see the black of the widespread Mag-Lite torches.
Hard-anodization seems to be rare. Jetboil-stoves had that before, but they changed to cheaper processes. The ceramic layer is a lot thicker with hard-anodization, it becomes visible and looks silky-aluminum-matt. Not sure if that can take colours the normal way, but i would prefer ceramic-coloured anyway.
Given the effort they put into the paintshop at Tesla, it might be a compaitivly efficient process. It would certainly give Teslas, already the most lasting cars by construction, the most invincible body - long shelf live would help the advent of the electric car i guess.

What do you think?
