conditioning the plastic trim

[waterkeeper03]

I have an 04 impala. I would like to know what is best to use to condition the black plastic trim that runs around the bumpers, and across the doors, and under the doors.

I am always careful to keep wax off of the trim, the cars paint still looks fantastic, but that trim is starting to loose it's color and turn white-ish in spots. just showing it's age. any suggestions?

I've used Back To Black; I'd heard about "Forever Black", but don't have the funds to order any yet.
