Having a dent removed from your car can be very expensive. Each dent in your car could easily run you £32 to £65 at an auto bodyworks garage. Don't get your wallet out yet, though. There a simple trick you can use to take a dent out of a car, and all you need is a heat gun or hair dryer and a can of Air Duster. Aside from the money you will save, this technique will also get the dent out without damaging the paint.

  1. 1

    Apply heat to the dent for 30 to 60 seconds. Hold the heat gun over the dent and slowly move it in a circular motion.

  2. 2

    Spray carbon dioxide (CO 2) on the dent with the Air Duster for ten seconds. Ice will form over the dent from the CO2.

  3. 3

    Wait for the ice to melt. As the ice melts, you will see and hear the dent begin to expand. Once the ice has completely melted, wipe the area with a clean rag.
