overview Germany Lauer Fahrzeuglackierung GmbH Mercedes-Benz Fleet Refinishing Contract

Mercedes-Benz Fleet Refinishing Contract

Touchup and refinishing of 15 demo vehicles with minor scratches and paint imperfections using our cordless air pistol system for precise application in hard-to-reach areas. Each vehicle requires specific color matching to factory standards.

Steps

1 / 9 | Vehicle Inspection and Documentation of Damage

The painters are meticulously inspecting each Mercedes-Benz demo vehicle to accurately document all scratches and paint imperfections. This involves a systematic examination under specialized lighting conditions to detect even minor defects that might not be visible under normal lighting. They are recording the exact location, size, and severity of each imperfection on digital tablets using specialized software that maps the damage to vehicle diagrams. The team is taking close-up photographs of each defect with measurement markers for reference during repairs. They're also determining the appropriate repair method needed for each defect – whether it requires simple polishing, touch-up work, or more extensive refinishing. During this process, they're checking factory paint codes and specifications to ensure their later color matching will be precise to Mercedes-Benz standards. This documentation will serve as the foundation for estimating materials, time requirements, and establishing the quality control parameters for the entire fleet refinishing project.

2 / 9 | Clean and Prepare Vehicle Surfaces for Painting

In this crucial preparation phase, the team meticulously cleans, sands, and masks vehicle surfaces that require repair. First, they thoroughly degrease all identified damage areas using silicone removers to ensure no contaminants remain. They then apply progressive wet sanding techniques with different grit papers (starting with 800 and finishing with 2000) to feather edges around scratches and create smooth transition zones. For deeper scratches, they apply body filler where necessary, shaping it precisely to the vehicle contour before fine sanding. Masking is performed with extreme precision using specialized automotive tapes and paper, creating clean lines while protecting surrounding areas from overspray. Special attention is paid to Mercedes-specific details like chrome trim and branded elements that require particular care. Throughout the process, they use compressed air to remove dust and conduct repeated inspections under bright lights to ensure perfect surface preparation before primer application.

3 / 9 | Color Matching for Mercedes Fleet Using Spectrophotometer Technology

The team is using advanced spectrophotometer technology to create precise color matches for the Mercedes-Benz fleet vehicles. This critical step ensures that each repair will be invisible to the customer. The process involves scanning the original factory paint on an undamaged area of each vehicle, analyzing the spectral data to identify the exact color composition, and then using the computerized paint mixing system to formulate a perfect match. The team must account for variations in factory batches, vehicle age, and exposure conditions that may have slightly altered the original color. For metallic and pearlescent finishes common on Mercedes vehicles, they're paying special attention to the precise ratio of metallic flakes and pearlescent additives to match not just the base color but also how light interacts with the paint at different angles.

4 / 9 | Applying Primer to Prepared Surfaces Using Cordless Air Pistol

The team is applying primer to the previously prepared surfaces of Mercedes-Benz demo vehicles. They're specifically focusing on areas with minor scratches and imperfections that have been sanded and masked. The cordless air pistol system is being used for precise application, especially in hard-to-reach and tight areas that would be difficult to access with traditional spray equipment. The primer provides a smooth, even base for the color coat to adhere to and helps fill in minor imperfections in the surface. The team is careful to apply the primer in thin, even coats to prevent runs or sags while ensuring complete coverage of the repair areas. They're also mindful of maintaining the proper distance between the spray gun and the surface to achieve optimal atomization and a consistent finish.

5 / 9 | Apply precision color-matched base coats using cordless air pistol for controlled application

The team is applying precision color-matched base coats to the prepared and primed areas of the Mercedes-Benz demo vehicles. They're using specialized cordless air pistols which provide greater maneuverability and control for reaching difficult areas and ensuring even application. Each painter is working with paint that has been custom-matched using the spectrophotometer technology to exactly match the factory colors specific to each Mercedes-Benz vehicle. The application process requires multiple thin coats rather than one thick coat to achieve the proper color depth and finish. Painters are carefully controlling spray patterns, distance, and overlap to ensure uniform coverage without runs, sags, or dry spots. Between coats, they're allowing proper flash-off time according to the paint manufacturer's specifications and the current temperature and humidity conditions in the spray booth. Throughout the process, painters are constantly checking the application quality under the specialized lighting to identify any imperfections that need correction before proceeding to the next coat or stage.

6 / 9 | Apply Clear Coat to Ensure Durability and Factory-Matching Finish

The team is applying the final clear coat layer to the Mercedes-Benz demo vehicles being refinished. Clear coat application is critical for providing durability, UV protection, and achieving the glossy factory-matching finish expected by Mercedes-Benz. The process involves careful preparation of the spray equipment, mixing the clear coat with the proper hardener ratio, and applying multiple wet coats with precise flash-off times between applications. Each vehicle requires 2-3 even layers of clear coat, applied in overlapping passes to ensure complete coverage without runs, sags, or orange peel texture. The technicians are using cordless air pistols with HVLP (High Volume Low Pressure) technology to achieve fine atomization while minimizing overspray, particularly important for the precise touchup areas on these high-value vehicles. Temperature and humidity are carefully monitored as they significantly impact the clear coat's flow, leveling, and curing properties.

7 / 9 | Quality Control Inspection of Mercedes-Benz Fleet Vehicles Under Specialized Lighting

The workers are performing detailed quality control inspections on the refinished Mercedes-Benz demo vehicles under specialized lighting systems designed to reveal any imperfections. Each vehicle is methodically examined from multiple angles to verify the perfect color match against factory standards and to detect any potential defects in the clear coat application. The inspection involves carefully checking for color consistency across panels, identifying any dirt nibs, runs, orange peel texture, or swirl marks in the finish. The team uses handheld light sources to cast light at various angles across the repaired surfaces, making imperfections more visible. They're particularly focused on checking the blending zones where new paint meets factory finish to ensure seamless transitions. Furthermore, they're verifying uniformity of gloss and depth of shine to match Mercedes-Benz factory standards. Any detected imperfection is marked with small adhesive dots for subsequent correction before final client delivery.

8 / 9 | Polishing Repaired Areas on Mercedes-Benz Demo Vehicles

The team is performing precise polishing work on the recently painted areas of Mercedes-Benz demo vehicles. After the clear coat has fully cured, the repaired sections require careful polishing to achieve the seamless factory-like finish that Mercedes demands. The workers are using a systematic approach of progressively finer polishing compounds applied with specialized orbital and rotary polishers. They frequently check their work under different lighting conditions to identify any imperfections, swirl marks, or inconsistencies in the finish. Special attention is paid to matching the exact gloss level and texture of the surrounding factory paint, as even minor differences would be immediately noticeable on these high-end vehicles.
