I recently got a used n3DS Xl MM Edition that is in perfect working condition, but has got quite a lot of scratches on the top and bottom of the shell. The scratches aren't very deep so I was wondering if I should buff the shell with some Maguiar's Ultimate Compound (it's a car polish), but I'm not sure if it will work. On the otherhand I could paint the entire 3DS. I was thinking about going completely black with maybe a design on the top. But if I paint the hinge would that effect the open/closing of the device? I want to disguise a scratch on it that bothered me quite a bit (I'm pretty OCD). Sorry for the long post, will upload pictures soon.
