Method 1 of 3: Preparation for Dent Removal
-
- 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).
-
- Use a hair dryer that contains multiple temperature settings you can manipulate, such as "Low," "Medium," and "High," or "Cool," "Warm," and "Hot."
Method 2 of 3: Heating the Dented Area
- 1
- Hold the air dryer between 5 and 7 inches (12.7 and 17.78 cm) away from the car's surface to prevent the paint from becoming damaged due to overheating.
-
- Turn on the hair dryer using its medium setting, then aim it at the dent for approximately 1 minute or until the car paint is warm when touched.
-
- Place a sheet of aluminum foil on top of the dent to keep the area insulated.
Method 3 of 3: Applying Dry Ice or Compressed Air
-
-
2
- 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. The liquid ice is a result of using the can of compressed air while it is turned upside down.
-
- 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.
