What are the drawbacks of filler-free dent repair?
2 Answers
The drawbacks of filler-free dent repair are that it requires a higher level of technical skill. If the technique is not up to standard, it may result in uneven surfaces or even thinning of the original material. Additionally, it is expensive and suitable only for niche vehicle models. Some vehicles with aluminum alloy bodies cannot use this repair technique. Below is a detailed introduction to automotive dent repair: 1. Introduction: Automotive dent repair involves restoring the dented parts of a car's paint surface to their original condition. Generally, this method can effectively repair dents with sharp or obtuse angles. Dents without paint damage can often be restored to their original state, including hail damage, though edges and AB pillars are more difficult to repair. 2. Traditional metal sheet repair: Metal sheet repair involves restoring deformed parts of a car's metal body, such as dents caused by collisions. The process reshapes the metal to its original form, followed by applying specialized paint to restore the surface to a smooth, glossy finish, matching the undamaged areas.
I had a small dent in my car before and heard that paintless dent repair (PDR) was quite convenient, so I gave it a try. However, the problem arose—this technique is only suitable for very minor damage, like small dents the size of a fingernail. If the dent is slightly deeper or near the edges of the door, it tends to rebound after repair, and mine reappeared within a month. Moreover, the technical threshold is high. If an unprofessional technician handles it, the tools might scratch the paint, making it even more costly to fix. I suggest everyone carefully consider the car body material before choosing this method. For example, harder metals like aluminum are more difficult to work with and have a higher failure rate. Although PDR preserves the original paint, its downside is its narrow applicability—it’s powerless against larger or more complex dents. In the end, I switched to traditional methods to avoid further hassle.
