On these Vics it is hard plastic trim with metal in it and it is stuck in with the urethane so you can break it flush with the body but the rest wont come out and that is what catches the tool.
Yea I know the trim and your right I have the same problem with the blade catching it.
I have a saws all made for windows with a putty knife blade that rips those stubborn windshields right out. If you were a bit closer I would have sent it your way.
