I have PPF on the front of the car along with the front and rear fender flares. I had a small accident where an Explorer and I got too close. It looked like it was messed up on the fender flares. PPF torn up. I pulled it off and there were only two little spots you have to look for to see. I would guess yours is probably fine underneath the PPF. I also had something hit the car on the way home. It looked rusty and the PPF was torn to the point of being able to flap it. Had it re-done and it was fine underneath it.
