Talismoon Displex Screen Polish and Scratch Repair Kit for PSP, Ipod, and more
Bought this stuff hoping that it might help a little.  It did absolutely nothing not even on the very small just surface scratches from the stylus pen!  It actually made scratches show up that I couldn't even see before!! Terrible product.  Go to Ebay and spend $15 to $20 and get a whole new screen!!
