Re: [ATM] Coating removal

I second this.  Strongly alkaline solutions attack glass.  Try ferric 
chloride solution available from Radio Shack and other electronics 
suppliers as circuit board etchant.  I don't know if it will go through 
the various overcoats, but it will take off aluminum and will be much 
less likely to harm glass.  Safety wise, it shouldn't be too bad.  Don't 
drink it and you should be OK.
