Hi i am looking at painting the plastic parts on my door trims could anyone tell me do they come off the pannel or do i have to mask the whole thing up???

Hi, I am looking at doing this too, so far i have read they are either glued or plastic welded to door card. (Removing the door card is easy enough)
Still need this clearing up though?
Also how do you remove the armrest from the door card?
