I just masked mine off. It came out pretty good. It was not all that hard. I would suggest that when you do decide to paint the trim, to give many small thin coats.
Removal is not recommended. Not only is it a PITA to get off, but it breaks the window seal so it has to be replaced. I would recommend very meticulous masking.
