PPF cannot prevent rock chips if the rock size is not tiny, then PPF will tear and it will look worse until re-PPF.
If the rock size is tiny, then it does not really matter even on a car without PPF, because it can be fixed without re-painting.
Also, the edge of PPF on a curbed corner area will collect dust and it will look worse than no-PPF (if the car color is a bright color such as silver or white).
PPF cost is already too high for the value of the car, and it needs do re-PPF if hitting by rocks is really happening.
What is the point of PPF then (if the cost of PPF is already expensive nowadays) ?
