Removing Scratches from CRTs

A friend brought me a load of old TVs and stuff he'd rounded up from city
trash day, and amongst them was a set I hadn't heard of a before - a Loewe
Calida. I thought it was an old studio monitor or something, but looking
around on the internet I see it is actually a premium - and pricey -
television set. Trouble is, it has a big ugly scratch along the top - very
shallow but still enough to hurt the image. Is there any way to remove, or
at least hide/mask, scratches on CRT faces? I have a number of nice sets in
my stock that have minor scratches and chips on the faces - nothing large,
just enough to reduce the sets value to the point where it isn't worth
repairing.
The Loewe is actually dead, I just wanted to see if I could repair the CRT
before trying to get the set going. Not a chance of replacing it - it's some
weird Philips "Black Matrix" which would be impossible to obtain.
Thanks for any advice.
