Have you tried C02?  I haven't used it for this application but have  
for others.  The trickiest involved removing a failing anticorrosion  
coating from a large Coreten Steel sculpture that had been treated  
with a rust converter.  We wanted to remove the anticorrosion coating  
but not disturb the converted layer below - C02 was the only thing  
that worked.  It was costly though but under the circumstances (we  
were in an airport beyond security), it was the only option.
