Any luck fixing iPad 2 screen scratches?
A friend's dog jumped onto my iPad 2 yesterday leaving a thin but deep scratch right through the center of the screen. I can clearly feel it and it produces an annoying rainbow effect especially when the screen is bright. I know Apple doesn't cover this under warranty and that replacing the screen costs $350+ from Apple, $250+ from local merchants and $150+ from DIY sites like this one: http://www.digiexpress.us/Replacement-Glass-and-Digitizer-for-iPad-2_p_301.html
Considering those costs, I feel like it wouldn't hurt to try patching or filling the scratch with something first, just to take the edge off the rainbow effect. I've heard you can use toothpaste, white erasers, or this iDrop stuff: http://www.amazon.com/PodShop-iDrops-Cleaner-Scratch-Remover/dp/B0006V7QAK however I haven't found any reports of people actually trying these things on an iPad 2. Is there some special coating on the screen that I'll be removing?
I know this question's been asked repeatedly, but I'm hoping to find some new answers.
iPad 2, iOS 5
