If you left your car outside during a recent hail storm, there are most likely dents on the hood and roof of your car. They are quite ugly, but you don't have to look at them forever. These dents can be easily removed with some dry ice and heat all on your own.
Identify All The Dents That You Want To Fix
Start by counting the total amount of dents that you'll need to fix. If there are only a couple dents, you will not need that much dry ice. If there are many dents, you should buy several pounds of ice.
Purchase The Dry Ice
Dry ice can be a little hard to find since it is not something that is left in the freezer section for the average consumer to buy. Call around to local grocery stores, hardware stores, and even butchers to see if they sell dry ice.
Before you rush off to the store, you will need a Styrofoam container to hold your dry ice, and heavy-duty work gloves to protect your hands when handling it. As a reminder, you should never handle dry ice using your bare hands. It is incredibly cold, and can damage the skin on your hands if you are exposed to it for too long.
Heat The Dent With A Hair Dryer
You will need to get out your hair dryer to heat up the dents, and extension cord as well to help reach all areas of your car.
Start by pointing the hair dryer directly at one of the hail dents on high heat, and keep it there for approximately 2 minutes. Then turn your hair dryer off, quickly put your work gloves on, and get ready to grab some dry ice.
Chill The Dent With Dry Ice
If your dry ice chunk is big enough to completely cover the dent, leave it there for approximately 3 minutes. If the ice chunk is too small, rub it in a circular motion on the dent so that all parts are exposed to the cold.
Take the ice off the dent, and watch what happens. The extreme difference in temperatures should make the metal contract, and the dent should pop out on its own.
Keep repeating these steps for every dent on your car, and be prepared to spend 5 minutes fixing each dent. If the heat and dry ice method is not working, you'll need to take your car to an auto body shop that can remove hail damage from your car.
