Let’s see how to get a dent out of a car at home. Yes, that is possible. You can get that nasty dent out very easily. Just read on and soon you’ll know how to fix a dent in a car. 

Before we can get into getting dents out of the car’s body, let’s first see what kind of a dent can be dealt with at home.

What Kinds of Car Dents Can Be Fixed at Home?

Before learning how to pull a dent out of a car, you need to know what dents can be pulled out. Here are the types of dents that you can fix at home: 

  • If the dent has not damaged the car’s paint, it can be tackled at home.
  • The dents which form a big depression on a body panel and not sharp indents can be pulled out.
  • If there are cracks on the dented panel, the dent can most likely not be pulled out.
  • Very large dents can not be suctioned out.
  • If the body panel is made of aluminum, the dent cannot be pulled out in the majority of cases. 

With that out of way, let’s now see how dents can be pulled out of a car’s different parts.

How to Take a Dent Out of a Car When It is On a Metallic Body Panel 

Before we can start exploring how to remove a dent from a car, we need to know the theory behind it. 

How are dents formed? 

The sheet metal that makes up the body panels of your car has atoms of the metal in an orderly manner. When the sheet is subjected to an excessive external force, it can result in two things: 

  • It can displace the atoms just enough to make a dent in the body panels of the car.
  • It can displace the atoms so much as to tear the sheet apart.

How are Car Dents Removed?

The aim is to realign the atoms of the metal the body panel is made up of. To do this, you need to apply a force in the opposite direction. However,  it must be noted that the metal can be restored only if it is deformed to a certain point. If the deformation is too much, the dent cannot be undone, not at home at least. 

DISCLAIMER: These are just some tips that can help you do minor repairs on your car. The actual results will depend on your understanding and execution of the steps. If you are not experienced in this type of work or think that you might not be able to do it the right way, get the help of a professional.
