Okay, so I got this 3ds XL off of ebay a while back and they had pictures of the thing's screen and everything. They said that the screen was in pristine condition and all that, but when I got it, there was a kind of deep noticeable scratch on it, and a few other lighter scratches. I was wondering what kind of polish should I use if any at all to make them go away, and to those who have actually tried polishing the screen what were your results? Did it make the screen like new or did it make it worse? Please help me out here. D: I've searched through google and all I got were vague answers or none at all.
