Although the CRT in question is off-topic, the question is fairly topical:
Is there any way to remove physical blemishes from the face of a CRT?
I've got a very nice 19" SVGA display that has some scratches on the face.
They are somewhat invisible unless you happen to be looking at something
at that part of the screen (lower third, right of center).
Can this be buffed out or ... ?
I hope there's a way to do this because I've been wanting to fix the face
of my 35" ProScan TV that has the same problem. You barely notice it, but
it is slightly distracting when you do.

Hi Sellam
It takes quite a bit of elbow grease but yes, it can be done.
Usually you use some 10 to 20 micron aluminum oxide to fine
grind until you are past the scratch. Then you use rouge or
cerium oxide to polish. It is a process similar to what we do
to make a telescope mirror.

Do I have to worry about any heat build-up that might cause a fracture of
some sort?
So sounds good so far. Can I just go to the local telescope store and
pick up the materials? Can I use my Dremel to do the polishing for me?

On the other hand, Dremels are good at melting things with their
super-fast motor. I'd recommend against using one. Anyways, with stuff
as fine as the aluminum oxide and rouge, you shouldn't need (or want to
use) anything electric to grind your monitor.
