Aha! Just found this on the wikipedia page on Aluminum Oxide:
Quoted message said:Aluminium oxide is responsible for metallic aluminium's resistance to
weathering. Metallic aluminium is very reactive with atmospheric
oxygen, and a thin passivation layer of aluminium oxide quickly forms
on any exposed aluminium surface. This layer protects the metal from
further oxidation. The thickness and properties of this oxide layer can
be enhanced using a process called anodising.
So anodizing is just a process to thicken and enhance Aluminum's
natural coating. Also, earlier in the article it talks about how
Aluminum Oxide is very hard, so it shouldn't come off very easily into
a white powder...
Once again, i think bare aluminum would be very cool and perfectly
okay.
