How To Remove A Dent In Car With A Hair Dryer 8 Steps

To achieve the best results, use this method on shallow dents that do not contain major creases or paint damage, and that cover a surface area with a diameter of at least 3 inches (7. 62 cm).

Heavy-duty insulated rubber-coated gloves. A full (or nearly full) can of compressed air. A package of dry ice. A hair dryer with adjustable temperature settings, such as “Low,” “Medium,” and “High,” or “Cool,” “Warm,” and “Hot. " Aluminum foil.

The hair dryer should be set to medium and should be held between 5 and 7 inches (12. 7 and 17. 78 cm) away from the car’s surface. Do not overheat the area in order to prevent the paint from becoming damaged due to overheating. [3] X Research source

If you are using dry ice, grab a block of the ice with one hand, then gently rub it over the aluminum foil resting on top of the dented area. If you are using a can of compressed air, turn the can upside down, and spray the surface of the dented area to cover the area with a layer of liquid ice. There are some basic principles of science at work here: the pressure, volume, and temperature of a gas are all interconnected. While normally the can loses temperature as the gas is released, if you spray the can upside down the gas itself is cooled. [5] X Research source Either method will only require a brief application. The surface panels of most modern vehicles are made of relatively thin and lightweight material and they will cool very quickly. You will likely not see any change after the first 30-50 seconds of application (or probably even sooner than that).

If you used dry ice, remove and dispose of the aluminum foil after the dent has been removed. If you applied liquid ice by means of compressed air, wait for the white foam to dissipate from the surface of the car, then wipe residue away with a gentle cloth.
