This was a frequent problem with the early generations of Roman numerals,
but newer technology now allows production of stainless Roman numerals,
which merely acquire a very light layer of surface oxidation which then
prevents further degradation and flaking as with rust.

I believe Google could provide more detail with a search using 
"stainless roman numerals" or something like that.
