Erase Engraving on iPad

Is there a way I can erase engraving on the back of my iPad without any kind of scratches?

My iPad4 is in very good shape and I don't see any reason to sell it. But the iPad mini inspired iPad5 design looks really great from leaks.

I will decide on selling my iPad4 once iPad5 releases. But only thing bugging me is....resale value because of engraving.

So, anyone tried erasing the engraving?
