T&T: Anchor chain painting

[Terry Neill]

Let's not forget about aluminum and some other metals. They are often  
left uncoated so that oxidation can occur. The oxidation layer becomes  
a protective barrier for the surfaces under it, often preferred to an  
opaque coating which would obscure other types of corrosion.
