Sorry to see that, I don't do PDR but I am a body man. That wont come out, its too stretched now. A PDR guy might make it better but they wont be able to get it all out.
Almost 75% of the work I do is for stuff like that, the person who hit it almost always is long gone and the car owner is paying. Probably 10% of the people that do the damage pay. Its a shame, the assholes that hit you just don't care. I dread leaving my car in a parking lot. Parking spots are way to small and nobody knows how to drive.
