Bumper dent repair paint generally does not come off. As long as the repairman operates according to the normal workflow, the paint will not fall off unless the workers fail to meet the standard or are lazy and save the process. Generally, for the sheet metal painting of steel exterior decoration, it is necessary to repair the concave part first, then polish it with putty, then spray primer, and then polish it with sandpaper of different labels, unless the primer is not sprayed or the sheet metal is not in place during maintenance, and the putty used is too thick.

Automobile repair method

Use hot water. At present, most of the front and rear bumpers of family cars on the market are made of special plastic materials. Boiling water can restore the sunken car body, and the reason is simple. Plastic will soften when heated, and it can be pushed out when it touches the concave part. Once the concave part is restored, please immediately use the prepared cold water to cool the place that has just been drenched by hot water, so that the rubber can shrink and recover.

Using dent repair tools, although the bumper has a strong plasticity, sometimes the strength of hot water expansion alone is far from enough to prop up and repair dents, so at this time, external force is needed. A set of tools online is only a few tens of dollars, which is still very effective for small dents. After purchase, it can be put in the car for emergency.
