Are you wanting to polish the clear plastic? If so, take a look at Novus plastic polish. I have used it in the past, and it has worked well for me.

Hello, Got my unit back (from cap rework) and the Deox(sp?) arrived so will be trying to fix the POT for the brightness and the memory switch. WIll reply back with updates after I've done some work with that. HOWEVER.... The next question I have is what works to help restore the clear plastic over the display (I've heard rumors about using the headlight defog stuff for surfaces like that... but no idea if it's safe) and then what to do with the white that is both dirty and faded. Is there a retro-brite approach? Or something better? I've had the case apart as I work on the other two parts, so would be a good time to work on the case... Thanks! Earl P.S. I've got a battery and Rex ordered for the unit.... so those will be attacked after I finish with the items above...
