i take them off all the time when i part these cars, i have what is called a long blade, its a 30 inch handle that takes a standard double edge razor blade, i slip the blade in from the top of the molding holding it tight to the car and start pulling, like cutting out a windshield, once the top is cut i push it down further and cut the bottom tape, molding falls right off, no bending or chance of wrecking, i have cracked them in the past with other methods, they will split, and instantly too, my blade method works the best for me, and with a new blade, i can cut all 4 moldings off in about 2 minutes. you canbuy a long blade anywhere, home depot, ace hardware, places like that.
