I was driving on the turnpike (highway), all of a sudden I heard stones hitting the front of my car,

there was a truck in the middle lane dropping rocks everywhere . I wasn't the only one affected by it. I tried to get away from it,but it was already too late. I have about 40 chips on the hood,fenders, and bumper. I dont want to repaint the car.
Advices please, methods of painting chips etc, polishing perhaps
