Interior plastic trim pieces

Hello all,



I've noticed that some interior plastic trim pieces have a rubber-ish black coating that can start to peel/come off (ex: the piece where the windows switches are, or the the back of the passenger door pull handle. Anyone else noticed this? Is there a way to remedy this or prevent it from happening? It appears to happen from normal use/wear.



Does anyone know if I can replace these pieces independently or are they part of the door cards?



Thanks!
