Repair skills of car body depression?

First, when the depression is deep and large, you can draw, heat with a glue gun, and draw the melted glue stick on the suction cup and pull it out;

Second, when the area of the depression is not very large, the depression can be sucked out by using the principle of optical lever force and strong magnetic attraction;

When the area of the depression is small, you can use a professional pry hook to reach the back of the depression and slowly pull it out at the depression;

First of all, the professional method is to insert the glue stick into the back seat of the glue gun, heat it for 3-5 minutes to melt it, then apply the melted glue to the suction cup, firmly stick the suction cup to the depression, and then pull it out to recover.

Secondly, if the concave area is not too big or too small, the concave area can be sucked out by the adhesion of magnetic attraction, and then leveled by the principle of optical lever, which is only suitable for concave areas without scratches.

Thirdly, when the area of the depression is small, or the above two methods do not work, the traditional method can be adopted, that is, using a professional pry hook to slowly "top" the depression from the back, which can also be well repaired.
