I have PPF on the front end and mirrors on my C7. Several years ago I was on the #404 N/B at night. I hit a patch a spilled asphalt at 110 km/hr. It sounded like a machine gun hitting my car. The front and sides were doted with black marks and small stones. The front end took the worst. Some areas of the PPF were imbedded with small stones and a few spots the PPF was torn. The PPF saved the paint otherwise I would of have to repaint the entire front end. I would get it again.
