Paintless dent repair (PDR) is a process to remove dents and other defects from the vehicle surface without using body filler or repainting. If the paint on the vehicle is damaged, the PDR cannot be used to repair the vehicle. Dents are usually repaired from the back. The main technique is to gently push the dents out a little at a time. Some tools include a special light that allows the technician to see the outline of the area being repaired, as well as a variety of metal picks and rods. The advantages of paint free dent repair include shorter repair time and lower cost. A typical dent repair with hands on the buttocks usually involves using a material called body filler to fill the lower part, make the repair area smooth and even with the rest of the vehicle surface, and then repaint the area to match the rest of the vehicle. Paint free dent repair avoids these techniques and can only be done when the paint is in good condition. If the paint surface is cracked, peeled or lost, trying to use PDR technology will make the damage more serious; The finished repair will need repainting in any case. The main technique in PDR is to gently push out the dent from the back, commonly known as "massage". This is a gradual process in small increments to avoid damaging the paint. If the dent is pushed too suddenly, it increases the possibility of the paint separating from the metal due to the force involved. Another reason for small steps is to avoid pushing the surface too far in the opposite direction, resulting in bumps. An important tool for repair of paint free dents is a lamp unit, which enables the technician to clearly see the outline of the damaged area. The lamp is long and rod-shaped. When it is placed on the paint surface, the reflection on the paint surface can be seen; A dotted line appears above the dent. When the dent is pushed out, the surface returns to its original shape and the reflection straightens until a smooth line is seen. If there is no energy in the light, the same effect can be achieved with a dent plate with dark and light stripes. Other necessary tools include specially designed metal pickaxes and rods of various sizes to apply mild pressure and leverage to the dents. The improved technology helps to popularize PDR and increase the number of qualified technicians. Stronger, more resilient paint on modern cars can successfully repair larger dents in this way. Repair can usually be completed in an hour or less, and the cost is much lower than traditional methods. Paint matching is difficult, time-consuming and expensive, but paint free dent repair avoids these problems by retaining the original finish.
