Removing Anti-Glare Coatings?

[Trash80toHP_Mini]

My newly liberated Studio Display has wear marks and scratches on its anti-glare coating. I just LOVE HP-Mini's glossy LCD and was wondering if anyone had experience with, or had links to good info on polishing CRTs/geting rid of damaged coatings?

I'll google it myself, but asking for pre-sorted, vouched for links has always paid off big time for me in the past! [] ]'>

I have heard of some people just peeling it off.

The screen is actually a lot brighter after you do so, but I don't think the contrast is as good.

I got really good looking 17 inch samsung from someone cause the coating had bubbled and peeled off leaving spots

after trying everything around the house and A ton of elbow grease, the 2 things that seemed to affect it the most were

Laquor thinner

90% rubbing alcohol (tho once the shop towel gummed up it stopped working)

A buffing wheel sped things up, but it was still a slow long process, once you start you cant really go back

And yes it does lighten up the screen, but contrast is 0 issue, it looked really good on this screen

Also tried it with a KDS monitor, using 1600 grit sandpaper, once the glass was buffed back out it didnt look any less crappy then before, but you will never get it crystal clear again (but the crt was fuzzy anyway so i tried)

I picked up a Mitsubishi Diamond Plus 93SB in the last couple of months. It looked *horrid*. A big patch of the antiglare had come off around some obvious scratches, and over time it'd left a splatter of lightness in the middle, surrounded by perfectly good antiglare on the rest. You're probably familiar with that.

I ended up using steel wool, the fine stuff you can set fire to, with a little ammonia-based window cleaner. Gentle rubbing without much pressure eventually took it off. In a couple of little spots I went down to another layer of what seems to be a half-millimetre thick plastic coating over the glass, where the antiglare on top was more like a very very thin varnish.

In the end I had all the antiglare removed with just a few tiny scratches where I went into the hard plastic protective layer. All up it's 95% perfect, but 10,000% better than it was with the glare coat scratches!

NICE! Good goin' , maniac!

I'll probably use some of my sign-painting/glass gilding tricks! [] ]'>

Elbow grease, Agua, Bon-Ami & medical cotton roll or seamstress' cotton batting to scrub the film off and polish the glass at the same time. That's how glass is prepped for gilding (for a mirror finish) and how excess gold is removed after the image has been backed-up with paint or SS Ink.

Bon-Ami is an American Brand-Name for a very fine chalk precipitate. It's about as fine an abrasive you'll find that's readily available . . . without delving into the esoterica of grinding rouges etc.

. . . and it polishes the snot outta' glass surfaces when scraped with a razor blade! }

. . . which might prove somewhat problematic on a CRT! :O

maybe, but on the face it would take a pretty hard hitting blade scrape (like in a batman movie or something)

Amoina based glass cleaner is something that did work well, but the towels were loosing abrasiveness much quicker, laquor thinner could damage the plastic coating (which i did not think of, but was high speed buffing at the same time).

Course its up to whatever particular mix of coating and application, but next time im defiantly doing the uber fine steel wool, or powder type abrasive, that seems to be the main key

Remember the old school way of anti glare, basically a piece of pantyhose streached over the screen, and if you were special you got the one that was directly on the crt, which was ruined the second some one poked at it, and you had to razorblade it off

luckily, our first monitor was that II series, monochrome with the power button on top and the satin finish tilt screen (simmilar satin look to LCD's today)
