Cor-Ten Steel

I am looking for information about conservation of cor-ten steel
sculpture displayed outdoors.  A search of CIN revealed 5 publications.
I know lots of work has occurred, but probably not been published.  I am
interested in treatments and maintenance procedures.  Thank you,

Helen Alten
