Ray...I did a large Corten piece which has been installed outdoors for almost 30 years.  Because of the copper in the alloy initially it rusts, forming a protective layer which, if left undisturbed, prohibits further rust.  The initial rusting causes severe staining around the sculpture...some kind of replaceable, well-drained footing (gravel, sand, etc.) is a good idea.  

The occasional graffiti written with a stick or rock has caused some minor continued rust.  I would be interested in your information to the contrary.
