Repair method 1: 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 sprayed out in the concave part as long as it is heated. Once the depression is restored to its original state, please immediately use the prepared cold water to cool the place that has just been drenched by hot water and let the rubber shrink back.

Repair method 2: use the sag repair tool.

Although the bumper has strong plasticity, sometimes the strength of hot water expansion alone is far from enough to prop up and repair the sag, so at this time, external force is needed, and the sag repair tool can just meet your needs. A set of tools online is less than 100 yuan, which is far lower than the cost of repairing in 4S shop.

The above two methods are more suitable for general bumper dents and help car owners to repair bumper dents without going to 4S shop. It should be noted that whether the front bumper or the rear bumper is sunken, you must be careful when maintaining it. Never get twice the result with half the effort. If it really doesn't work, we'll send it to the repair shop. I believe they have easily solved the problem of bumper depression.
