Hello -- I wonder whether any MMDers have advice on treating the
following situation: the glass on one of my instruments has been
painted (inked) with a design or decal on the reverse side and now,
with age, the paint is beginning to crack, craze, and peel.

Is there any recommended treatment to slow or stop this?  I wonder
whether a spray of gloss polyurethane (or lacquer?) on the reverse
side would help stabilize the situation or make it worse.  Any ideas?

Thank you!
Tom Sendall
