Simplex Plastic Rejuvenation
I have a Super LJ front derailleur with a Delrin insert. I don't believe the Delrin is structural- more like a decorative insert. (Unfortunately I'm having issues adding and posting from Flickr from my phone).

The plastic part has "dried out" and has turned grey- I don't think it's under any stress, so it shouldn't matter if it cracks- but I was wondering if anyone had a good tip how to keep the Delrin looking nice and black.

Would ArmorAll or WD-40 or something bring that back?
