Possible to recoat AR layer on CRT screen?

[Radiohead]

ARGH!!! Somehow I managed to take off a bit the AR coating off the screen, and now there's a smear that's a little over an inch long running down the center of my screen and it's bugging the heck out of me.

Is it possible to get this fixed? I'd like to keep this monitor.

sandpaper works wonders!

Try applying some clear candle wax and buffing lightly with a clean soft cloth.

Sounds like you scratched off the anti-glare coating that is put on almost every monitor these days. You're going to be hard pressed to fix it if that is the case. The coating is applied at the factory when the glass is pressed and I have never heard of anything to repair the coating short of removing it and having it reapplied. I've never heard of anyone doing that!

If in fact you have scratched the actual glass you might try a windshield repair kit you can buy at automotive stores. It will not repair the integrity of the glass but it might reduce the effect somewhat so that it does not bother you as much.

That's a toughy. You could try totally removing the anti-glare coating, then using an external anti-glare attachment. I don't know how you could do this, but I guess it's possible. If the glass is still scratched underneath, try the automotive glass repair kit that the previous poster mentioned.

clear nail polish?

Try some car wax. It will take out some small stuff. Plunk a bunch down and then rub until smooth. It works well on scratched CD's.

For really small scratches (on CD's, negatives and maybe even a monitor) you can use forehead oil...yeah, gross but it works.

Forehead oil?

No one's mentioned this, but is it possible to use your warranty to get the screen fixed? Before you start ripping off the anti-glare coating and all.

It's the AR coating that I scratched, not the actual glass itself.
Now to dig out my warranty... with my luck it probably expired the day before this happened.

I guess I scratched it when I was wiping away some of the dust using a paper towel and some glass cleaner for eye glasses...

Maybe the eyeglass cleaner has some solvent in it? They usually want you to clean the screen with just a damp cloth I think.

If that happened to one of my precious monitors I would probably try to take the coating off the rest of the screen and hopefully be left with clean glass.

Well, whatever you do, DO NOT apply nail polish or anything oil-based to your screen. The anti-glare stuff is a plastic layer and would be completely destroyed.
If you are going to remove the anti-glare anyway... doesnt matter! (I think it will be hard though...)

The most common application of the coating is done via a spin coat process, where the face of the CRT is pointed up, then spun. Droplets of the coating are applied to the center of the tube during the spin process. The centrifugal force makes the coating spread evenly over the face of the CRT. The CRT is then heated to cure the coating.

Better coatings are applied via a vapor deposition process.

Unfortunately if the coating is scratched or damaged it is virtually impossible to fix without replacing the CRT. Buffing the scratched spot usually will only remove more coating and make the problem worse.

Thanks for all the responses... anyhow looks like I'll be getting a new monitor all together now.
