    • Once finished, you need to ensure that affected area is hot enough before proceeding to the next step

Kindly take note that any overheating done on the area will cause damage to the metal.

  • Next step is for you take a can of air duster
    • Turn it upside down before you start to spray it over the dent right after heating the area with your hair dryer

It is also important for you to hold the can of air duster upside down in order for its content to produce liquid forms. Make sure that no liquid drops onto your skin because it is harmful to human skin.

    • Then, you have to wait for the ice to melt
    • During the ice melting process, you would be able to hear a popping sound coming from the dented area. That means your dented area has returned to its original shape
    • Any excess of liquid needs to be wiped off by using a clean rag until you see no more ice left on your vehicle
