In fact, when the fender is sunken, we can suck it out with an electric sucker. First, put the electric sucker in the concave position of the paddle, suck it, and then pull it out directly with great force. Of course, before using the electric sucker, we can use the principle that plastic becomes soft when heated to heat the concave part with hot water to improve the efficiency of repairing the concave part. Finally, after the depression is restored to its original state, it is necessary to use cold water to cool down, thus playing the role of contraction and recovery.
To repair the sunken part of the fender, it is necessary to suck out the sunken part first, so it is impossible to keep the original paint surface. Generally, it can only be solved by sheet metal re-spraying, and it is difficult to repair it without damage. You'd better go to the garage to have it repaired. Personally, it is not recommended to repair it yourself. You can not do it first, and then insure it together when you have more next time.
1. If the paint of the dent has been damaged, everyone who knows it knows that it is difficult for technicians to find it during maintenance. The most important and crucial point to repair the car dent is to find some. Failure to find them in time will only make the dent worse and worse. Without rich experience in repairing cars and finding technicians who are not as clean as fire, there is basically nothing to do about this dent. The second one is touch-up, which is also very technical, but it seems to be very unskilled. Many car owners are getting less and less ugly when painting, just because they don't know the skills of painting. The repair technician can repair the damaged paint to 80% (of course, it will never achieve the effect of painting);
2. The depression is very sharp. On a line where the paint has fallen off, due to excessive stress, the sheet metal has folded two ridges of nearly 90 degrees. Repairing these two ridges is not an easy task. Moreover, the wheel brow ridge of the sheet metal itself has almost disappeared due to excessive stress, so it needs to be repaired. The sharper the depression, the higher the requirement for finding points. If you find something wrong, there will be obvious pits after repair, which is a great challenge for technicians.
The area of this depression is as big as two palms. Such a large depression is very sharp. Repairing it not only takes a long time, but also tests the patience of technicians.
