Cosmetic Repair

i recommend you use a product specifically designed to polish plastics. a product i've found to work very well is plasticare. it's made in englewood, colorado. i live in colo and am able to buy it at a couple of well-stocked hardware stores or from the factory. don't know about availability in other areas. if you can't find this exact product, look for another designed to clean/polish pexiglas.

The polish you can get to remove scratches from Audio CDs should work here. It is plastic afterall. Discwasher makes a CD polish and scratch remover I have used successfully on damaged CDs.

Their are plastic polishes sold at marine/boat stores that are used on fiberglass boats. I have used them on clear plastic souviner snowdomes (my wife's collection) with very good results. They polish but do not leave scratches (that I can see). Their is a bottle around here somewhere that I cannot locate, or I would mention a brand. You would want to do a test as with anything. I have never tried then on plastic that is other than clear.

DK, have you tried the boat polish on CDs? Sounds better than toothpaste which in my experience leaves discernable marks.

Audioplus if the finish of the monitor is glossy you might get good results but if it's not and does have some texture or grain in it I'm affraid you'll end up with a glossy patch compared with the rest of the plastic. Maybe just very limited fine grit sanding will be enough to lessen the problem but it will depend on how the plastic surface is iluminated. If you use a plastic care product be certain that it's OK for the plastic material you're dealing with. This will diminish the gloss increase but before doing anything try in an area of the TV that is not that visible like behind the set. Hope this helps
