Got this from a reputable source (carcareonline.com). Might explain the blotchy black and grey emorcus is talking about:
-----------------------------------
If raw silicone oil based products have been previously applied to the rubber/vinyl, the raw silicone oil has saturated the material. One Grand E.R.V. or 3M Rubber Treatment will help dissolve out the silicone oil (this is good) but do not seem to be able to do so evenly (this is bad). The finish may be slightly splotchy after the first couple of applications. The only solution is to apply several coats about a week apart and the finish will eventually even out.

Use a polish on the plastic get a clean microfiber pad an do it by hand the black will start to gloss again. Then get some exterior dressing an put some all along the platic black trim pieces. When you detail cars with a ton of black plastic pieces you get use to restoring/protecting the trim.
