What is the best colour restorer for black plastic trim which has faded?

What is the best colour restorer for my black plastic trim which insists on staying grey?
Our Interior Car Care shortlist is here: kit.honestjohn.co.uk/awards/awards-2019/interior-c.../

You'll see the Meguiar's Quik Interior Detailer in there. In our opinion, that's the best option for cleaning interior trim. However, for restoring the colour of black trim - Meguiar's Ultimate Black Plastic Restorer is very good: amzn.to/2VoHdTG
