Shiny black window trim

[carld]

Good evening,

Can anyone help me or advise me how i can get hold off the black glossy door trim that sits at the top of the door and meets the window, one has started to lose its gloss effect and has started to discolour.

I would try polishing it by hand first as they are painted and then clear coat applied. Its probably just oxidised

I used t-cut cream on mine and it worked well.
