Hi, whilst the mini suction cup could be used to remove a shallow dent on a vehicle, this is not its primary function. It is ideal for picking up and placing flat, smooth items such as ceramic tiles, polished aluminium or glass objects, phone/ laptop screens etc. For a shallow dent on a vehicle you would need to remove any silicon polishes or oxidation with an appropriate cleaner and then place the suction cup over the are and squeeze the handles together to form a vacuum and then gently pull the cup upwards to withdraw the dent. Several attempts may be required.
