How to Fix a Dent in a Car?

Professional workshops employ this technique for car dent removal. It is versatile, applicable to various deformations across different vehicle body parts. The process involves mechanical manipulation from the inside out with a specialized dent removal tool tailored to the specific dent. Successful application of this method also demands skill and experience to avoid damaging the vehicle’s body or paint.

The choice of dent removal technique depends on the dent’s type and size:

Cold Forming: Best suited for minor dents that are not deeply embedded in the body, this technique utilizes tools like a dent lifter or dent removal pliers to push the dent from the inside.

Hot Forming: This method is aimed at larger, deeper dents. To ease the deformation of the paint and body, heat is applied around the dent using specialized equipment such as a heating lamp or infrared heater. The dent is then pressed out with suitable tools.

Pushing and Pulling: This technique involves addressing the dent simultaneously from both the inside and outside. While a dent removal tool pushes the dent from the inside, a corresponding pulling tool extracts it from the outside. These methods may not be effective for all types of dents or damages. For complex or deep damages, it’s advisable to seek professional assistance from a bodywork specialist.

1. Hot Glue Technique for Flat Surface Dents Without Damaging the Paint

Ideal for small dents on the vehicle’s body, the hot glue method is popular among DIY enthusiasts. It requires minimal skills and a few tools. Hot glue is applied to the dent, and a combination of a pulling hammer and special glue is used to extract the dent from the body. Ensuring the glue is hot and fluid guarantees strong adhesion to the surface and a solid bond. A specialized pulling tool, such as a dent removal bridge or pulling hammer, is then used to pull the dent out slowly and evenly. After removing the glue, the dent should be significantly reduced or completely eliminated.

It’s crucial to note that the hot glue technique is suitable only for dents that don’t extend deep into the body. Care should also be taken to avoid paint damage during adhesive removal.

If unsure about using the hot glue technique for your damage or if the dent is deeper, consulting a professional auto body repair specialist is recommended.

2. Compressed Air Dent Removal Tool for Curved Surface Dents

For compressed air dent removal using suction cup technology, as implied, a suction cup is placed on the dent. The vacuum created then pulls the damage out of the body, effectively for smaller dents without affecting the paintwork.

To address larger dents, a professional suction cup with a pneumatic connection is placed on the dent. A compressor generates a vacuum, securing the suction cup against the body, allowing a dent removal hammer to smoothly even out the treated area. This method requires patience and careful handling to ensure the dent is removed without causing additional damage. For deeper or more extensive dents, seeking professional repair services is advisable.

3.Home Remedies for Small Dent Removal

For accessible small dents, such as those on the hood or door, consider these DIY solutions:

Hot Water and Cold Spray:

Pour hot water over the dent and immediately apply cold spray or an ice pack. The rapid temperature change causes the material to expand and then contract, facilitating dent removal.

Hair Dryer and Cold Spray:

Another method involves heating the area around the dent with a hair dryer, then applying cold spray or an ice pack.


Minor dents can also be addressed with a suction cup plunger. Press it against the dent and pull gently to remove the dent with minimal effort and cost.

These methods may not be successful for larger dents, in which case professional auto body repair services are needed. If effective, our tips can help restore your vehicle’s appearance, complemented by our guide on professional aluminum polishing for a mirror finish on rims, fittings, and more.
