Query: HORRIBLE and RUINS your product.

I searched long and hard for a product whose title was, "Plasma tv screen scratch repair" and I thought I had found it. If you type that phrase in the Amazon search bar, this product is the first product to appear.Great reviews so I figured, this is finally it.I got it in the mail from Amazon and read and reread the instructions and what happens? Scratches still there and my screen is ruined! It takes the protective coating off of the screen and does nothing for the scratches.No customer service from Amazon as this is from a third party seller. I have contacted the manufacturer and was basically told that I have to contact the distributor... after contacting them, I get an automated email telling me to contact Amazon.com.I am SOOOOOO Not happy!
