I bought this product because I had dropped my PSP between the couch cushions and when we put the recliner up it had a scratch on the screen, It wasn't horribly deep, but bad enough to bother me. From what I could tell this would have solved my problems, but it didn't. It came out a runny liquid, I followed the instructions but the scratch was still there, so I tried it once by letting it sit overnight and still nothing. I have tried this product a total of around 8 times on the same area, it was the worst investment I ever tried. But what was I expecting from a cheap 6 dollar product?
