[AlanLee]

For door dents, ordinary household car suction cups will suffice. Below are specific details on using car suction cups: Applicable situations: Used to repair not very severe dents, ordinary household car suction cups can be employed. Suction cup principle: Using a suction cup to repair dents leverages the difference in atmospheric pressure inside and outside to adhere to the object. This small suction cup can be used to fix minor door dents by attaching it to the dented area. If the dent is larger, prepare several suction cups and evenly attach them to the center of the dent. Tools can be used to pull outward with force, requiring skillful handling to prevent the dent from protruding.
