I will try to take some this evening. It will be hard to get w/o getting the car on a lift. I haven't actually seen the damage yet myself, just felt it when I pulled the offending tree branch out.
If the crack can't be seen from normal angles and the intent is to stop any spread, you have a wide choice of repair methods. Fiberglass resin and the matting it comes with will stick to the urethane just fine...
