1. Blow the air outlet of the blower towards the depression of the car. You can't be too close. If it is too close, the paint will melt due to high temperature, so it should not be too far away. If it is far away, the repair effect will not be achieved.
2. After the blower blows, prepare a shelter to cover the dent, and you can choose aluminum foil, because aluminum foil has very good thermal insulation and can keep the dent warm to the maximum extent.
3. Put dry ice on aluminum foil. In order to prevent burns, you must wear heavy gloves and clamp the dry ice on the aluminum foil with a bracket.
After the dry ice is put down, if the dent is small, there is no need to move back and forth. If the dent is large, it is necessary to move the dry ice back and forth to cool the dent evenly.
5. After a period of time, if you hear the sound of metal, it means that the car dent is recovering.
