How to paint the back of an iPod?

Question

Do it yourself

Preferably without removing the sticker.

Answer 1

Are you sure you don't want to paint the front?

Answer 2

If you do not remove the sticker - not the fact that you get a normal result.
And so - remove the back cover, remove the lock switch and the headphone jack from it, sand it, degrease it, paint it with paint on metal from an airbrush, dry it for +60 for a couple of hours, varnish it and dry it again.
You can cover the sticker with paper tape or other sticky material that can be easily torn off and carry out all the above operations around the sticker.
