Use a plastic filler spreader and push it behind moulding. Scrape the whole way round the outside edge. And then it will come off. Start from top left and go right and underneath Back left again. They are time consuming removing adhesive and refitting though. Prob best to buy a new one, paint it and fit that as it comes with the tape on it. Or mask car and paint it on... I would do that if you were just painting the moulding.
save all the messing about...
