I've been posting few posts about car dent repair and trying to convince that car dent removal is not an expensive job and can even be performed by some household items. Regarding this I've come up with another way of removing car dents, and it can be done with the help of a hair dryer and CO2. So all you need is a hair dryer and a liquid CO2. Even a spray can can of carbon dioxide can be used. I will tell you how to make the spray can emit CO2 in liquid form. So when you are ready with these two items just follow these steps and witness that fixing car dents is too easy and cheap. Note that the experience of many people has revealed that the diameter of the dent should be at least 3 inches in order for this method to be effective. Now coming to the method.

1. Heat the dent with the hair dryer for approximately 30 secs to 1 minute. Make sure that the panel is hot enough when you are done.
2. After heating it spray CO2 on the region. Make sure that you hold the spray can upside down while you spray it. The reason for this is that CO2 comes out in a liquid form when you spray it upside down.
3. The panel will be covered by a foam of ice. You just wait and listen until you hear a popping sound which tells you that the metal has retained its original shape.
4. When the white foam disappears, clean the area with a piece of cloth.
5. The dent is no more there.

This technique does not cause any harm to your car paint so you don't need to worry about it. The secret is warming the metal hot so that it expands so this technique is very effective and works well in warmer regions of the world.

P.S Many people have said that using even a boiling water instead of CO2 even does the trick. I cannot say anything because I haven't tried it yet. If any one has done it then you are welcome to share your experience. Anyway watch the video of the above procedure.
