Douglas,

I had the same problem, and you came up with
the only solution. It proves the hypothesis that
CeO has a chemical bonding with the glass. It is
actually under the surface. Did you also get a
rainbow effect?

Hello,

I am polishing my mirror (10" BVC) and after a polishing session, I always
seem to end up with a thin,
blotchy, hazy film of CeO on the mirror.  It makes it difficult to judge how
well the polishing is
going.

I have been taking the mirror directly from the tool to the sink and rinsing
it off, using soap, etc.
but the film never really goes away.  Is there any trick to avoiding this
problem?  The only
thing that seems to remove the film is more polishing...

Thanks,

Doug Braun
