Hmm, interesting. I wonder if there are any chemicals that'd either kill
off the mould (if the CRT was left to soak in a bucket of them) or
destroy the glue in order to remove the outer layer (so it could be re-
glued) - all without totally destroying the tube completely.

Probably not - the heated wire trick sounds difficult on anything but
the flattest tubes though :(

At least the tubes aren't dead in the case of our HP stuff though, which
is good news :) (an HP 250 with a mouldy screen is way better than no
250 at all)

Funny how - apart from a couple of other screens out of maybe 300 - I've
only seen it really affect the HP stuff.

Well certainly with car windscreens there's no cure that I know of
except for a new screen, but then that's a much bigger and more complex
piece of glass...

cheers
