The door handles on my '97 T-5 have faded from coal black to dull gray. The bumbers and side moldings are looking a little faded too. What to you guys use to freshen up the exterior plastic bits and make them look new? I've tried Griot's rubber and vinyl dressing, and that makes them look nice for about a day but then they look faded again (I don't think it soaks into the hard plastic the way it soaks into rubber). Griot's also sells some stuff with black dye in it specifically for faded black plastic. Anyone ever try it?
