I had to pull the plastic trim around the steering column, to fix a lighting issue. The plastic was faded grey, much like the fender flares. To restore the original look, I first tried Meguiar's Ultimate Black. All that did was make the black look blacker, but the grey was still there (1st picture).
Next, I broke out the random orbital buffer, along with some Meguiar's Cleaner/Polish, and buffed the plastic. After about 5 minutes of buffing the factory black returned, which can be seen in the 2nd picture. FWIW, I tested picture #2 by repeatedly washing the plastic piece in soapy water. After 1/2 dozen washings, it was still as shiny as the picture!
Pictures 3 and 4 are another piece, before and after.

Picture 1 - Test with Meguiar's Ultimate Black (Shiny, but still grey). Also, this washed off easily with soap and water, returning to a dull grey.

Picture 2 - Random orbital buffer used, in combination with Meguiar's Dual Action Cleaner/Polish. After 5 minutes of buffing, the grey was gone. Also, this was washed repeatedly, with soap and water, but the shine stayed and the the grey didn't come back.
