Almost every vehicle gets at least a few dents and bumps. There are several different methods of minor body damage repair that customers can choose from. PDR, also called paintless polishing, is a machining procedure that is sometimes used as an alternative to traditional body restoration. This method allows the technician to repair the dent or dent without damaging the paint.
The difference between traditional smoothing and PDR
Typical or traditional body restoration involves using sandpaper to chip away at the paint, hammering and returning the metal to its original state, and then filling the areas with putty. Then the specialist sands and sprays with primer, base coat and the last coat of paint. This procedure may cost more than several million and take more than a week to complete.
Paintless refinishing or PDR involves working on the opposite side of the panel where the damage occurred. In fact, the metal is slowly drawn and returned to its proper place. In addition, a direct light tool is used to ensure that the exterior is smooth. Repair costs are usually lower than traditional methods and can usually be done in less than a day.
Smoothing methods
There are many methods for smoothing, and choosing the most appropriate method depends on the type of damage, the material of the part, the amount of budget and the employer's priorities. Some common methods are:
Smoothing with hammering: This traditional method is done using hand tools such as hammer and anvil and requires high skill and experience. Paintless polishing (PDR): In this method, using specialized tools, minor dents on the car body are removed without damaging the paint.
Smoothing with a suction device: This method smooths the depressions on metal surfaces by using vacuum suction. Laser smoothing: An advanced method that corrects dents and indentations on the car body using a thermal laser. Smoothing with putty and sandpaper: This method is used to fix more extensive damages that are accompanied by scratches or fractures and is usually accompanied by repainting.
