Removing a dent from the body of your car can be simple if you know how. While the easiest method involves using a special tool designed specifically for the job, you can also choose from a few other methods, many of which only need common household items. Keep in mind that the following methods are meant for small-to-medium-sized dents. For any dent too big, consider consulting a car body shop.
Lean how you can remove a dent by using a specialty tool, a plunger, by applying hot and cold, or how you can use an ordinary vacuum for paintless dent removal.

Use a Specialty Tool

Using a tool specially designed for the process represents one of the best ways to get a dent out of a car. To use a pop-a-dent tool, follow these steps:
Step 1: Attach tab. Attach the puller tab to the deepest part of the dented area using hot glue.
Allow the glue to set to the point where it no longer has any stickiness and is only tacky.
Step 2: Set up puller. Feed the threaded shaft through the hole in the dent puller and attach the handle.
The dent puller uses the pads attached to either side to provide counter pressure to the threaded puller tab in the middle of the device.
Step 3: Use puller. Turn the handle, which in turn pulls the puller tab away from the body of the car.
Keep tightening the handle until the dent is gone.
Step 4: Tap down high areas. Using tools designed for the job, such as special hammers and taps, tap down any ridges or high areas around the dent.
Step 5: Repeat as necessary. Repeat the steps above as necessary until the dent is removed and the body of the car is smooth.
Step 6: Clean up glue. Using a cleaning solution, remove any glue once the dent is removed.

Use a Plunger

You can also use a plunger to remove a dent in the body of a car. This method of paintless dent removal works best with shallow or small-to-medium-sized dents. The following steps detail this method:
Step 1: Lubricate the plunger. Apply petroleum jelly around the edge of the plunger to act as a lubricant.
Step 2: Apply the plunger. Place the plunger against the dented area and gently press in to form a tight seal.
Step 3: Remove dent. Pull the plunger away from the body of the car.
The suction from the plunger should pull the body of the car out along with the suction, hopefully removing the dent.
Repeat if necessary.

Use Heat and Cold

Using alternating heat and cold, you can coax the dent into popping out on its own. The rapid change in temperature through the natural expansion and contraction of the material can help fix a dent to your vehicle. The easiest way to apply heat involves the use of a hair dryer, while compressed air can provide an easy way to cool the body of the car once heated up. The section below covers this process in more detail.
Step 1: Apply heat. Using a device such as a hair dryer or heat gun, apply heat to the dented area.
This step should take no longer than 30 seconds to complete.
You can also use hot, boiling water to heat the material of the body of your car. This works especially well on plastic body materials, such as on plastic bumpers.
Step 2: Cool the metal. Next, apply compressed air to help cool the heated area.
If done correctly, the cold air should help the metal pop back into place.
Dry ice, another alternative to compressed air, can rapidly cool car body material, causing the dented material to pop back into place. Make sure to wear the proper protective equipment when using dry ice, such as rubber gloves. Also remember to protect your car’s paint from the effects of dry ice. You can do this by putting a sheet of aluminum foil between your vehicle and the dry ice.

Use a Vacuum Cleaner

You can use the hose of a vacuum to pop out a small car dent by using a pot or a bucket with a small hole in it and following these steps.
Step 1: Secure bucket or pot over the dent. Remember that the bucket or pot should have a small hole that the vacuum hose can completely cover. Use tape to fix the pot or bucket to the surface of your car. Make the seal around the bucket or pot as airtight as possible.
Step 2: Put the vacuum hose over the small hole and turn it on. The suction created by the vacuum will hopefully help a small dent pop out!
No matter how it happened, getting a dent in your car is annoying and irritating. But by using the above methods, you can easily remove small dents and bangs from the body of your car. This helps save you the expense of taking your car to a body repair shop. If the dent is too big, however, you should consider seeking the help of a professional to prevent further damage from taking place.
