Black trim.

I use this:

It puts the black back into faded plastic, leaves a lovely mate finish and will keep beading up for months.

With the plastic trims prep is everything! I would recommend CarPro DLUX or Gtechniq C4. These steps will help you get the suggested durability

1. Scrub them a stiff brush and a strong APC solution, something around 3:1 and rise with water after every section. You don't want to let strong chemicals dwell on plastics.

2. lightly soak a microfibre towel with tardis and massage into plastic a few feet and a time and rinse regularly.

3. Re-wash with car shampoo. Not one with any built in wax or such!

4. A wipedown with IPA or a panel wipe (eraser etc) can assure a clean surface but not entirely necessary.

5. Dry the trims completely. water will effect the coatings and can cause streaks

6. Apply product as per instructions. Optionally you can heat the plastic with a heat gun (be careful common sense will guide you on how much heat is too much) this will open the pours on the plastic and accept the coating better (this also works great on tyres)

7. Leaving the car indoors overnight will also help maximise durability. Water will halt the curing process on these products

These steps will also help maximise durability on dressing style products. I would highly recommend Gtechniq T1.

The low-tech approach is ground nut oil. Found in most decent supermarkets, costs buttons, and the bottle will last years.

It does a great job but will need repeat treatments. But as others have said, prep is key. The trim must be completely clean before applying. Apply the nut oil like you would any manufactured treatment, sparingly and with an applicator pad or small sponge. Also, wear gloves, cos that stuff gets everywhere.
