Fixing small scratches in plastic door trim around windows

[MyFirstAbraham]

There's a few small but visible scratches in the black shiny plastic trim on the edge of door windows.

Is there a good way to mask / hide them ?

I've used Plastix in the past, but it behaves differently on different surfaces, and with the door trim plastic being shiny I'm afraid to alter the appearance to where it's more obvious than before.

Is there some wax / resin type stuff that is more permanent than the regular wax and can mask these scratches ?

Also, what's the proper term for these parts ? If they are relatively cheap perhaps I can just replace them.

TIA

I just used Plastix on all the black plastic pieces last week and it made quite an improvement.
