Get ready for a stupid question . . .
I have an '02 Impala LS. What should I do to take care of the black vertical window trim (window frame?) at the rear of the front doors and the front of the rear doors. Just in case I'm not calling it the right name, I'm not referring to any felt, vinyl, or rubber weather-stripping, but rather the metal (or plastic, I don't know) part of the door that forms part of the frame for the window.
Do I wax it? Do I use some kind of protectorant? I want to minimize fading and UV damage.
