.5" scratch on my touch screen. Fixes?

[harrisonk]

I've got an htc touch pro2 with a plastic touch screen and there's a half inch long very shallow scratch on the screen, but deep enough to make it visible when the screen displays white (it sort of distorts the red-green-blue under the scratch). Is there any type of plastic repair product that can be used to buff this out? I ordered a case and screen protector but I'd like to get rid of this scratch before putting it on.
