Aluminum Corrosion

I would like to know what colour corrosion on 'mill' finish (unfinished) aluminum exposed to the weather would look like?

Hi, Mitchell

Although it would vary a bit depending on the particular alloy, I think the overall answer is that the corrosion will be manifested as crusty white pockmarks / volcanos.
