You can easily repair small dents on car body at home. First of all wash the damaged area of car to remove lubricate or dirt. Take a dent removing kit and a plunger and apply it to the injured area to create suction. Once suction is created, start drawing the plunger in outer direction to pop the injured metal back to its normal position. Plunger can easily move around on damp surface therefore you can move the plunger to the other dented area.
