When repairing the concave part of the automobile hood, you can put a suction cup around the concave part, or put a suction cup in the center, and then pull the suction cup up with a suction rod to restore most of the concave part. Hot melt adhesive can also be applied to the deepest depression, and the sunken hood can also be repaired by pulling up the hot melt adhesive with a pull tab.

1, sucker

When the car hood is sunken, it can be repaired with suction cups. After several suction cups are prepared, put the suction cups around the concave part with a suction cup in the middle. Then pull the sucker up with a suction rod, and most of the depressed parts can be recovered.

2, hot melt adhesive

Hot melt adhesive can also be used to repair the sunken hood. After drying the dent and finding the deepest part of the hood, apply hot melt adhesive to the pull tab and immediately stick it to the deepest part of the dent. Press the pull ring tightly for seven or eight minutes, then pull the membrane on the bridge, and the concave part of the range hood will be pulled up.

3. Local heating

After locally heating the concave part of the engine hood, immediately spray water or apply wet cloth on it, and let the heated part cool immediately, so that the concave part of the engine hood steel plate will shrink immediately, and the central part will generate tensile load at the periphery, which strongly counteracts the tensile load generated during deformation, and also achieves the purpose of repairing the concave.
