Key Techniques Professional Panel Beaters Use to Repair Smashed Vehicles

Car accidents can happen anywhere, not just on roads alone. Some of these accidents are as minor as a broken headlight, while others are as serious as a smashed bonnet or frame. Although a mechanic can do repairs on the former, severe dents can only be taken care of by a panel beater. Auto-repair professionals can restore your car's form by conducting extensive repair work. This article highlights specialised skills that panel beaters use to restore a smashed vehicle.  

Planishing -- When a panel beater receives a smashed car, they typically assess the extent of the damage before deciding on how to proceed. Once the panel beaters are done with the assessment, planishing begins. The technique involves gentle tapping on the dented or smashed section to flatten and restore to the previous form. To achieve the best results, panel beaters use light blows to smooth the area. However, the dented region must be hammered out, roughed, and blocked before planishing begins. Hammering brings the dented section close to its original shape, thereby allowing the panel beater to planish with ease. A professional panel beater uses a planishing hammer for this task.  

Putty Filling -- Even after flattening a dented car, the surface is not 100% flat since tiny dents are still present on the surface. Moreover, a car with severe damage always has holes that must be filled no matter the size. To fill out these tiny dents and holes, a panel beater prepares a putty mix and sets it into the indentations and holes. As the panel beater does this, they continue shaping the metal surface to ensure the putty filler forms the shape of a car's exterior. However, putty mixes set and get hard pretty fast. If a panel beater applies the putty mix a few minutes late, the mixture might dry unevenly.   

Panel Sanding -- After planishing and applying a putty mix, the prepared surface must be sanded thoroughly to make the smashed area level with the rest of the car. Panel sanding is necessary for extra smoothing of the putty-filled sections, and panel beaters generally use both dry and wet sanding. Dry sanding ensures the rough surface of the putty filler is smoothed out. It also removes the colour coating around the smashed area. After dry sanding, a panel beater turns to wet sanding to clean off the debris and to prepare the car for spray painting.
