1, insert the hot melt adhesive stick from the back of the glue gun, and let the glue stick enter completely. Insert the glue gun into the power socket, raise the temperature of the glue gun, preheat it for 3 or 5 minutes, and let the hot melt adhesive melt completely. Then select the appropriate traction gasket according to the diameter of the dent, pull the trigger of the glue gun, and apply melted glue on the traction gasket. It's sinking slowly. If there is a protruding part in the drawing, knock it back and forth with a rubber hammer and a special wooden pen until the concave part is mixed with the car paint. If the dent repair is not ideal, this step can be repeated, but it is generally difficult to restore the dent to its original state only by drawing repair technology. Generally, gentle depressions can be repaired by traction. If the above repair process cannot restore the sag to its original state, we need to use the second jacking method to repair it.

2. The top repair needs to be carried out from the reverse side of the sheet metal, so the general repair needs to remove the door trim panel, remove the interior trim panel, find the screws fixed on the door panel, and remove the screws. Break the buckle that fixes the door panel, take off the wire harness on the door panel, and fix the door panel with a fixing rod, so that the gap position on the door can be generally used for maintenance. Jack-up repair needs to insert the tool into the car door with a lever tool, and move the tool to find the sunken position and push out the sunken metal sheet gently and evenly until the metal sheet melts into the car paint, and the radian of the car paint is exactly the same.
