Paintless dent repair (PDR) tools are a set of specialized tools that are used to remove dents from the body of a car without damaging the paintwork. These tools are commonly used by auto body repair technicians to repair dents that have been caused by hail, door dings, and other types of minor impacts.

The basic principle behind PDR is to use specially designed tools to massage the dent from the inside of the body panel, working it back into its original shape. This is done by carefully manipulating the metal from the inside of the panel, using a series of rods and picks.

PDR tools come in a variety of shapes and sizes, and can be used to repair dents on any part of a car, including the doors, fenders, hood, and trunk. Some common PDR tools include:

• Glue pullers: These are used to apply a strong adhesive to the dent, and then use a specialized tool to pull the dent out.

• Slide hammers: These are used to apply force to the dent from the inside of the panel, in order to push it out.

• Reflectors: These are used to help technicians see inside the panel and locate the dent.

• Picks and rods: These are used to manipulate the metal from the inside of the panel, in order to push the dent out.

Overall, PDR tools are an important part of the auto body repair process, and are used by technicians to repair dents and dings in a way that preserves the original paintwork of the car.
