Query: Works.

It does work. I would only use it on an older TV. I used on my old Sony 32" Trinitron. That's an easy TV to do because, while it is curved, it is only curved in one direction.Be prepared -- you're picture will be fuzzed. But, if you are just trying to make an old glass screen TV work for you in a room with a lot of glare... it works great. Increase the sharpness and brightness. It will seem odd at first but live with it a while before scraping off. There isn't a lot of detail in a regular TV anyway and you'll see that you are just losing the illusion of detail.Do not use this product indoors! My TV is heavy and I opened all windows for ventilation and had to evacuate the house the rest of the day! It is nasty stuff. :-(I recommend putting marks along the tape (you tape off around the screen) to guide the spraying back and forth. I can see where it is a little uneven -- you won't get it perfect but it will still work and you only notice the unevenness when the TV is off.
