More than 90% of the scratched parts of the car are car bumpers. In general, the bumper is only slightly scratched, deformed or cracked. Going to a repair shop or a 4s shop can basically help you restore your original appearance.
The main function of bumper is cushioning and decoration. The impact on safety is not so great, and serious collision mainly depends on the anti-collision beam and longitudinal beam of the car body. So the bumper was only slightly scratched and the paint fell off. Only grinding, putty, painting and other steps are needed. After the repair, there is basically no impact, just like new.
If the tear area is small and it is not an important supporting position, it can be repaired by painting. Moreover, there are many repair methods now. Some bumpers are modified polypropylene, that is, plastic, which can be welded with homogeneous materials, that is, plastic strips and nails, which can basically achieve good results.
However, if the tear area is large or located in the load-bearing part, it is recommended to replace the bumper with a new one. Because the tear area is too large, even if it is repaired, the car will crack again because of vibration or slight collision when driving on the bumpy road. And it depends on what car it is. If the bumper is expensive, the cost of repair is also very high. Try to replace it with a new one if it is insured, and consider repairing it if it is not insured.
In fact, the repair of the bumper is relatively simple, and the difficulty lies in the local painting of the damaged part. Because no matter which part is repaired, the paint in the later period is not the original car paint, and there will definitely be color difference, which depends on whether it can be seen by the naked eye after painting. The focus of local painting is the joint, how to make the joint grinding inconspicuous or difficult to distinguish.
Xiao Ku tried it, and the door was scratched with a slender scratch, and the primer was gone. I went to two repair shops. One suggested that I spray paint locally, and the other suggested spraying the whole door. This is because local painting is difficult, especially some rare colors, while overall painting can guarantee at least one color of a car paint.
There are many factors that cause color difference. The first is the service life of the vehicle. There is little time difference between the newly sprayed paint and the original car paint, and the smaller the color difference is. If the car has been used for ten years, the paint on the car body has faded, and it is easy to see the color difference by spraying the bumper or door of the new car. Secondly, the quality of paint and the painting skills of masters. Some master painters have treated the paint surface and even achieved the effect of baking paint.
