There are a few steps that you need to do to get rid of car dents, though it is usually impossible to get rid of dents that are more than 8 inches in diameter without calling a professional.
Use a Plunger
The first thing you can try in your car repair is to “plunge” the dent with a plunger. Do this by pressing in and pulling out the plunger a few times over the dent. Many times, this simple step will fully remove the dent.
Hot and Cold Experiment
Another way to remove small dents is to heat up the dent with a hair dryer. Once the dent is hot to the touch, spray it with a can of air duster. The extreme cold of the air duster hitting the hot dent will usually pop the dent back into its original position.
Another cold thing to try is to place dry ice onto the dent. Dry ice can cause severe damage to human skin, so it is important that you use gloves when placing the dry ice on the surface of the dent. The dent should return to its original position after only a few seconds of contact with the dry ice.
By trying these simple home remedies, you can fix the damage on your car without a huge detail bill.
