protecting the plastic on the battery cover

[piratedninja]

what do you all use to protect the skinny piece of plastic with the htc logo and the 2 holes for the flash and camera? you know the long black piece on the battery cover.

I've noticed that mine has started getting scratched and was wondering if there are any screen protector type things to put on it so it doesn't keep getting scratched.

so far ive tried putting a piece of clear scotch tape on it after cutting to size but that seems to just come right off when i put the phone in my pocket.
another thing ive tried is cutting a thin piece of clear plastic and gluing it on with clear glue gel (dries water clear)
ive also tried just putting a layer of the glue gel on the back but that came off after the 2nd time of pulling the phone out of my pocket

are there any other methods that you have tried and works well?

I have one other method which involves super glue and a thin piece of plastic(which i know will work flawlessly) but i'd rather not go that route because i wont ever be able to remove it later on
