If it is not a serious accident, but the car shell is a little sunken, then try not to paint the car body, but adopt the method of "sunken repair". To put it bluntly, concave repair is plastic surgery. Basically, no materials are needed. It all depends on knocking and pulling, just like Huang Hong's sketch, a hammer is 80! 80! 80!

At present, the general labor cost is much higher than the material cost, so even if you repair the sag, you can't go to a 4S shop or a repair shop without two or three hundred dollars. Repairing the depression requires skill and experience, but it is simple and easy to understand, and most people can understand it at a glance, so for those who like to do it, you can try it.

For those who don't want to spend a penny, you can pound it from the inside out with a wooden stick. For example, this Haval H6 accidentally scraped the flower bed when reversing at night, which was 0.5 cm concave and 10 cm long. If you go to a 4S shop for repairs, you must first sheet metal and then paint the whole door. I can't get down without 500 yuan.

If you do it yourself, it will be very simple. Find a mop and make a simple tool.
