E53 X5 upper black trim.. how to revive?

[TurnAround]

I've read about "Black Wow" and "Back to Black" for the vinyl. I'll try one of those. My current issue though is the black B & C pillar post trim adjacent to the windows. Its paint... I think. I Zaino the car's paint, but have always left the black trim to its own devices. Last detailing, 5 months ago, I Zaino'd the painted black trim too. Surprisingly, it really took a toll on the the black trim. It has faded dramatically and "splotched" significantly. It really looks bad now. What do I need to do to bring this back to factory? 3M Finesse It swirl mark remover? 3M compound polish? Steel wool? A mild polish.

And, once I get it back to factory ... so, do I just avoid Zaino'ing this trim, or should I protect it with something else?

Thanks guys!
