Silver Aluminum

Can I use a silver / polished aluminum on the back of the iPod touch deleted without negative side effects?

I bought it used. I understand that I can not fix the scratches on the screen. However, can I improve the return to degree, without negative side effects? Can I have a silver / polished aluminum ....

It will not hurt anything but it will probably not help much either. Simply use the polish sparingly. Do not throw a ball for him there ...
