OK, I have this nice TV that has a couple of small scratches on the
glass. Is there a safe way to buff out the scratch? Normally it would
not be a problem, but this set will be used for a close up application,
and it's really irrating at the required distance I need to use it from.

If the scratches are not too deep, you can polish them out by
a sequence of grindings with successively finer grits. This
is long and tedious, but is the technique used for preparing
surfaces for metallographic examination -- which is also used
for preparing glasses and ceramics for microscopic exam at
times.

Alternatively, one could attempt to fill in the scratchs
with something with the same dielectric constant vs. frequency
(i.e., same index of refraction vs. wavelength). Water-glass
comes to mind (sodium silicate solution in water) as a possibility.

I would try the water-glass first. If it is not good enough,
it can be removed with water-based solvents. If it is good
enough you can seal it with a clear coat of your choice.

For a CRT I would NOT recommend flame-polishing, which otherwise
would be my first choice for descratching glass.

Tim,
My experience and observations tell me that you will only make the scratches
in your CRT more obvious and worse by trying to buff them out.

You could try that eyeglass scratch remover although I've heard it's not as
good as the TV ads say (big surprise).

I think I would use an optical epoxy to fill in the scratch,not try to
polish it out.Scratches are kinda dangerous in CRTs as they provide a start
for cracks,like you would do for "cutting" glass;scribing it.

Say,have you seen those TV ads (USA) for the product to fill in scratches
on eyeglasses? WalMart carries it,in their pharmacy section where the
eyedrops are located.AND,it sells for less than what the TV source sells
it! "As seen on TV"....

It might be worth a try.

$15 USD,IIRC Opti-Clear is the name,or something similar.

It is also carried by Walgreens,I believe.

Yes I have been looking at that kind of stuff since reading the reply
that suggested water glass. I am also shopping around for a windshield
repair kit, which is kinda the same technology.

I think that kind of fix would be much better and safer than polishing
or buffing.

Thanks to all whom replied to my question. I'll post the results when I
make the repair.

What about that stuff they use to repair cracked windshields? Or is
that no longer available either?

I had one with two 'digs' in the safety glass. We used a windshield repair
kit on it with reasonable results.

Unless it's non-AR-coated polished glass, this sort of approach will likely
make it worse.

I bought a tube of the stuff. Applied it as directed and it did an
extremely lousy job.

I think it's $4 a gallon acrylic floor wax put into fancy bottles.

The TV ads show a BOTTLE of the stuff,not a tube.
