How to fix the scratches on iPhone 5?

My iPhone 5 got scratched from the back a little bit and I don't wanna use covers and that things because it won't look like iPhone 5 and it will look like any other iPhone so is there any way to remove the scratch? By a cream or painting or any other way

Thanks

It's called ghost armor. Find somewhere that puts it on. It fills in scratches and keeps your phone protected.

Lots of people are touching up the anodised aluminium using sharpies and there was a link to this product on the mac foums (see below)
