The process generally involves using the suction cups of the plunger to attach to the dent and slowly pull it out, or using a glue stick to attach a bridge puller to the dent and then unscrewing the puller to lift it out. However, it's important to note that DIY dent repair kits may not be suitable for all types of dents and might not always provide a professional finish.
If the dent is large, deep, or located in a complex area, it's recommended to consult with a professional auto dent repair service to ensure proper repair and maintain the value of your vehicle.
