1. Collision Repair
This area focuses on restoring vehicles damaged in accidents. Collision repair specialists are trained to work with different types of materials, from steel and aluminum to composite plastics, and utilize specialized tools and techniques to repair structural damage, align frames, and replace or repair damaged body panels.
2. Dent Repair
Dent repair is a specialized area that focuses on removing dents and dings without resorting to traditional bodywork, often preserving the original paint. There are multiple approaches, including paintless dent removal (PDR), where technicians use specialized tools to gently massage out dents from the inside, and traditional dent pulling, which utilizes specialized equipment to pull out the dent.
3. Bodywork
Bodywork involves repairing the damaged body of a car, often after a collision. This includes tasks like replacing damaged panels, straightening bent metal, and preparing surfaces for painting. Bodywork technicians use specialized tools like hammers, dollies, and sanders to expertly shape and restore the vehicle’s body.
4. Paint and Refinishing
This involves restoring or enhancing the paint finish on a vehicle. Paint and refinishing specialists are highly skilled in color matching, mixing paint, and applying it using advanced techniques to achieve a flawless finish. They also handle other paint-related work, such as removing rust, applying primer, and clear coating.
5. Glass Repair and Replacement
Windshield and window damage are common occurrences, and glass repair and replacement specialists are adept at repairing minor cracks and chips or replacing damaged glass. They utilize a variety of specialized tools and techniques to ensure a secure and watertight installation.
