I know that aluminium oxide forms a non-porous protective layer, as opposed to iron oxide 9rust) which is porous and as such spreads throughout the metal.
So in theory it should be no problem to have a bike frame that is bare aluminium. Unpolished, unanodised, unpainted, as raw and as dull as they come.
What's it like in practice? Any reason why I NEED to get it clearcoated/anodised etc.
