I think the silver colour is inside the plastic, so when it fades it's not possible to renovate it. I had partial success on the same trim on a BMW by coating it with silver sellotape gift wrap tape, but sadly after the car had been left out in the sun, it went brown.
I suppose you could do a similar thing using pipe lagging tape (you know, the self adhesive tin foil tape). You'd have to cut thin strips and apply this, then refit the trim carefully to avoid damaging the surface of the tape. At least this would change colour like the plastic tape did.
I've seen people use washing up liquid to ease the plastic trim back into the rubber, but seeing as this can damage rubber, and contains salt, you'd be better off using baby shampoo, wash 'n' wax or even something like hair gel.
