1
Get a small clean drain plunger. Use the simple style of plunger without the flange in the bottom.
2
Clean the body of the car so that it is free from grease and dirt.
3
Put a bit of soapy water on the rim of the plunger, not too much. This will help the plunger create suction against the clean car body.
4
Attach it to the car body over the dent. Create an adequate amount of suction.
5
Slowly pull the plunger until the dent is gone.
