How to Fill Rock Chips

Rock chips are paint chips in a car, especially one frequently driven on roads with loose gravel that sends tiny stray rocks flying up off the road, where they hit the car and chip its paint. Neglected rock chips leads to unattractive nicks and chipped paint that can even rust over time. Filling your rock chips early on, however, saves your car's paint job. The task is relatively quick and easily and requires materials you probably have in your garage or that you can find at a hardware or home improvement store.
