Small bumps and dents are part and parcel of driving a car. They’re so common that you can get one from any situation – like backing your car into your garage. Use a hairdryer and an air duster to fix it. Heat the dented area with the dryer for a minute or so then immediately spray it with the air duster. Most small dents pop out easily this way.
The hair dryer heats the body, which causes it to expand, and the duster or canned air then cools it down immediately, causing it to contract. The pressure then causes the dent to pop out.
You can also use a regular plunger to pull out a dent. Place the plunger over the car’s body, ensuring it is securely sealed and then pull it up. The pressure relieves the dent almost immediately.
