Removing a dent from a car can sometimes be expensive, especially if you take it to a repair shop. However, there are alternative ways to repair and remove some types of dents from your car with the help of household items such as a hairdryer and dry ice or cans of compressed air. Read this article to learn how to remove dents using these tools.
Step
Part 1 of 2: Preparation Stage
Step 1. Locate the dent in your car
This method is especially useful for removing small to medium sized dents. Maybe, it turns out that these dents are quite a lot in your car. Check your car carefully so that all dents in the car can be found.
Step 2. Evaluate your car dent
Usually, dents can be removed this way if they are on the metal panels of the trunk, hood, doors, roof, or fenders. This method is not effective for dents along the edges of flat surfaces.
For best results, use this method on shallow dents that do not have large crevices or paint damage, and cover an area of at least 8 cm in diameter
Step 3. Prepare the necessary materials
You'll need a hairdryer, heavy-duty gloves or thick rubber for handling dry ice or liquid compressed air, foil, and a dry ice pack or can of compressed air. you need a number of following equipment:
- Gloves for heavy duty rubber coated.
- Full (or nearly full) can of compressed air.
- Mr. dry ice.
- Hairdryer with adjustable settings, such as " Low " (low), "Medium" (medium), and " High” (high) or " Cool " (cool), " Warm " (warm), and " Hot " (hot).).
- Aluminum paper.
Part 2 of 2: Heating and Cooling Dentized Areas
Step 1. Heat the dented area
Turn on the hairdryer to heat the dented car and the surrounding area for 1-2 minutes.
The hairdryer should be set to the medium setting and held at a distance of 13-18 cm from the surface of the car. Do not overheat the car surface to prevent paint damage
Step 2. Cover the dented area (if possible)
Spread out a sheet of aluminum foil to cover the dented area. This step should only be performed if you are using dry ice instead of compressed air. The purpose of this step is to keep the dented area warm while protecting the car paint from dry ice.
Step 3. Wear thick gloves for heavy work
These gloves will protect you from frostbite or other injuries that can occur when your skin comes into contact with dry ice or liquid compressed air.
Step 4. Apply dry ice or liquid compressed air
The rapid change in temperature from warm to cold will cause the surface of your vehicle to first expand (because it's heated) and then shrink (because it's cooled).
- If you're using dry ice, take a block by hand and gently rub it on the foil covering the dented area.
- If you are using a can of compressed air, turn the can over, and spray the dented area to cover it with a layer of melted ice. There is a basic principle of science at work here: the pressure, volume, and temperature of a gas are all related. While the can usually loses temperature when the gas is released, if your can is turned upside down while spraying, the gas will cool.
- Both of these methods can be done quickly. Most modern car bodies are made of thin and light materials and cool very quickly. You probably won't notice a difference after the first 30-50 seconds.
Step 5. Wait a moment
Some time after applying dry ice or compressed air, you may hear a popping sound indicating that the dent is gone. Rapid changes in temperature will usually make the material return to its original shape.
- If you are using dry ice, remove it and discard the foil once the dent is removed.
- If you apply liquid ice using compressed air, wait until the white foam has disappeared from the surface of the car. After that, wipe the rest with a soft cloth.
Step 6. Repeat the process as many times as needed
Your car dent can probably be removed with one repair. If the dent has healed but is still visible, you can start the heating and cooling process again. However, don't overdo it (especially in one day). While successive temperature changes can reshape your car's exterior, extreme cold temperatures can damage your car's paint.
