I’m not sure when it became the norm, but I’m guessing that somewhere around the 1980s, automobile manufacturers started putting unpainted, black plastic trim all over everything. And I hate the stuff. You’ve seen it, heck, you might even own a vehicle so equipped. Bumpers, rub strips, windshield wiper cowling, mirror housings, grilles. The stuff is all over the place, and it seems like an inevitability that it will, eventually, look like crap.
Dressings can make it look a lot better. Clean the item well, and apply the dressing per the directions on its label. Detailing e-stores and auto parts store shelves are crowded with products called “Black Eternity” and “Trim Fixer Upper.” Some of them work pretty well. But most of them don’t. Inevitably – even with the best trim dressings – your trim will look gray, weatherbeaten, and ragged again. Hopefully, your dressing won’t have run down all over the rest of your car in the meantime (you did wipe off the excess, correct?)
Anyway, we’ve all had it with this stuff. I’ve found the fix. Re-dye it.
This is a process that isn’t always practical; it’s best when done on trim that can be removed from the vehicle. On an E46 BMW 330i ZHP I recently did, for example, there was a large expanse of black plastic honeycomb covering the air intake for the radiator. The car owner might know how to remove this piece, but I, as a detailer, certainly shouldn’t disassemble the front bumper of a $40K+ car.
If it’s something that can be removed somewhat easily, though, I think re-dyeing the trim is the way to go. Here’s a re-dye of the mirrors on my personal F250.
Before starting, they looked rough, weatherbeaten and fading. They’re famous for this, and dressings only make them look better temporarily:

I took them off the truck and masked off the glass so I wouldn’t get any overspray onto it.

Wipe them down with some sort of body solvent:

Spray with the plastic dye of your choice. The one I used is made by Malco:

After you’ve applied the dye, reinstall the items, and admire the improvement:

So, there you have it. If the plastic trim you’re working with can be removed from the vehicle without damaging it, try redying it. It’ll look much better, for much longer, than it ever could with simple dressing.
