Need advice - Cleaned plasma with Windex

I have a 50" Panny Viera Plasma (TH-50OX80U) purchased from Costco a year ago. I have it set up in an outdoor living area in our backyard. A guy doing some work on the house noticed the screen had gotten dusty and decided to clean it with Windex. Before he realized what he was doing he had taken off 4-5" square section of the AG coating from the center of the screen. Very noticeable and very bad. I decided to have him keep rubbing and remove the entire coating. The picture looks fine in the dark but as you can imagine in an outdoor environment the glare has gone from marginally acceptable to completely unacceptable during daylight hours.

I am looking at the option of putting on an after-market anti-reflective coating similar to what you see for laptops, iPads, etc. Any thoughts on this approach? The NuShield product looks best so far. (Sorry, being a Newb member I can't post the link.) Is this something you would recommend for this type of use? Any other ideas or suggestions? Your time and help is appreciated.

I was afraid that's what you guys would say. To answer some of the specific questions:

• Parts of the coating came off very easily and parts were very difficult to remove
• Yes, he is a friend and he feels awful about what he did. He immediately offered to replace the screen or entire TV (The cost would be about the same)

Interestingly, yesterday we hung some curtains to block the reflection and it worked great. It looked much better than not having curtains WITH the anti-glare coating. I may try to come up with a way to make that work on an ongoing basis.

I appreciate the input. I've been a frequent lurker here and have always found the answers to my questions before. This is one of the best online communities going.
