The methods to repair scratches on the front bumper that expose the primer are: 1. Toothpaste has a grinding function. Using toothpaste is equivalent to applying a layer of wax to the vehicle, which can achieve a good repair effect. However, toothpaste can only be used for minor scratches and is not very effective for deeper ones. 2. Using a touch-up pen can cover some small and shallow scratches, making the marks less noticeable. The above methods are only suitable for minor scratches. If the plastic bumper is severely scratched, it needs to be repainted at an auto repair shop. The front bumper itself is made of plastic, so even if the primer is exposed due to scratches, it will not cause the paint to rust. Even if the scratches are not repaired, there will not be much impact.
The bumper on my car also got scratched down to the primer a few days ago, and I fixed it myself. The steps were quite simple: first, clean the scratched area with soapy water, then gently sand it smooth with fine sandpaper to remove burrs and dirt. Next, choose a touch-up pen that matches the car's color and apply it little by little, waiting for each layer to dry before applying the next. It took about three layers to cover the primer, and finally, I sprayed on a layer of clear protective varnish. The whole process took an afternoon and saved me hundreds in repair costs. But be careful not to choose the wrong color—it's best to use the VIN to check the original factory paint code. Doing it yourself might not be perfect, but the results are good for covering flaws and preventing rust, extending the bumper's lifespan. If you have time, it's a fun project and a great way to learn some car detailing skills.
