what kind of sandpaper should i use to sand chrome back

does any1 know wut type of a place would do this 4 me. im an idiot so if i did this it would turn out like that http://youtube.com/watch?v=qg1ckCkm8YI . so any suggestions, i dont no wut to look up in yellowpages or any other search. pretty much oblivious

Does anyone know if the Invisible Shield will work on a Brushed ipod? I was thinking of etching a design on my ipod, but i don't want it to stop the Invisible Shield from sticking.

bump for suggestions..

I don't know what to do it with. Some people say the green side of a sponge. Some say steel woll. I don't want to use sandpaper.

my ipod will never be scratched, its been in a case since day one, and its in mint condition, but wen it DOES scratch...i will do this, lol and as for the design? it will rock.

The warranty is not voided, and I think you should use a brillo pad.

Used my skullcandy stencil :]

Result:

i dont know if anyone else mentioned this, but why even ask if you're going to make a stupid reply like that to someones suggestion. a suggestion they took time to write.
think about what you're trying to do before you make threads for once.

Joseph your brush job is sweet. What did you use?

With the green side of a dish washing sponge.
If you do this... make sure you wear a mask or something and wash your hands after you've finished... I accidentally inhaled some of the metal dust and now I'm really sick xD
