I had the impression that the door handles and trim were aluminum just like the front driver and passenger door sills. Aluminum is a really soft metal that scratches and nicks easily as people are finding out. I know the door sills can be Xpel'd to protect them from grit from the bottom of your shoes but given the curvy nature of the interior door handle don't see how trying to wrap it would ever stay on, especially since you are always grabbing it to open the door.
