the stuff you need would cost 3-4X a new monitor. for glass you need wet sanding sponges from 100 grit to 5000 grit, polishing pads from 2000-5000 grit and a bag of tinoxide to make a polishing paste and it takes hours. i think you would destroy an lcd with the pressure you have to apply to it. i have these glass showcases in my restaurants that cost upwards 5-6k each ( 2 per location , 3 locations) and little shits will carve all kinds of dirty words in them when no one is peeking so i bought all this stuff to save the 1000.00 deductible3-4 times a year.
