100% true. late last year driving on the freeway i heard a bad sound. turns out something bounced off the road and hit my front bumper to the point it removed the top layer of paint in a spot about the size of a half dollar (and the ppf and the ceramic coating). this was after the paint correction, ppf and ceramic coating had been applied. had to remove it all, get the bumper repaired and reinstall everything.Plus, no matter how much protection you do (PPF, ceramic coating etc), there will come a day when your car gets a ding of some sort. It's inevitable.
