I think we have the biggest and oldest metal mailbox on the street. I had to wire brush it this last summer as there were just too many layers accumulating. It still has the layered look that is so fashionable among painted mailboxes- well at least that's the fashion that my mailbox prefers. My mail lady even tells me when it is time to paint something new. She tells me when she begins to grow bored of one design. I am not offended just inspired at that!
