To prevent rock chips and pitting in front of the car, the traditional solution was to install a custom vinyl black or you wait for the bumper to be damaged enough and then paint. Neither solution was very attractive.
Now there is an answer to all problems chips of rocks and road debris. It is generically called a paint protection film. Several familiar names are in the business of manufacturing the film: 3M, Avery, Venture Llumar.

The original developer of the film was 3M and it was used in the Korean War to protect helicopter rotor blades. 3M later redesigned for application to the front bumpers and hoods of vehicles.
With an improved design to adapt the film for the automotive industry, the idea took off. The concept was unbeatable. Car owners can now apply the film to the bumper and cover to drive the car everywhere without worrying about getting a rock chip.
Initially, each plant was cut to size from a bulk roll and carefully applied to painting. It was time and a lot of experience required. The idea took a while to sink in conventional vehicles.
While the increased demand for protection, new businesses pushed design kits that could be cut on a plotter and applied to the car. Therefore, another segment of the paint protection film industry was born.
