For friends who are not very skilled in welding torch operation, it is best to leave it to the garage. After all, this plastic hot-melt method requires professional instruments and pays attention to the maintenance process, which can be said to be beyond our solution.

As for how much it costs to repair the bumper, it is generally 300~500 yuan, but if the whole bumper is replaced, the price will definitely be much more expensive, at least 1000 yuan.

Some bumpers are only scratched on one side, and a professional master will advise you to repair half of them, because the painting technology is good and there will be no color difference. Of course, if the customer requires or there are scratches on the left and right sides of the bumper, then the whole pole can only be painted. Full bar painting can avoid color difference, but the cost is relatively high. So the specific price depends on the damage degree of the bumper and the size of the painting area.

If the scratch on the bumper is slight, it will be solved as soon as it is polished, but if it is slightly serious, it is recommended to buy a refill pen to make it up yourself. The price of online touch-up pens is only tens of dollars. It should be noted that the touch-up paint must follow the scratch, so that the touch-up paint effect will be better, but if it is the scratch of the primer, you have to go to the repair shop for plastic painting.
