The Mercedes Benz Sl 500 roadster, a vehicle synonymous with luxury and performance, boasts a timeless appeal. This particular SL500, cloaked in Aegean Blue Metallic and powered by a robust 302HP engine, came equipped with the coveted AMG Sport Package, enhancing its sporty demeanor. While not the full-fledged AMG SL55, this SL500 offers a driving experience that feels inherently “right” from the moment you slide into the driver’s seat.
Despite its low mileage of only 7,000 miles, this garage-kept beauty was in need of a comprehensive detailing session. The owner reached out seeking a thorough clean-up to restore its pristine condition. Upon inspection, it was clear the paintwork was swirl-free, a testament to careful ownership. However, the car presented its own set of challenges: an accumulation of scratches and stubborn water spots marred the horizontal surfaces, while the exterior was veiled in a layer of dirt and heavy brake dust, particularly noticeable on the wheels.
Knowing this detailing wouldn’t yield the dramatic paint correction transformations often showcased, the focus shifted. The goal was to meticulously document the often-overlooked areas in automotive detailing, offering an educational insight into comprehensive car care. This detailed walkthrough aims to guide enthusiasts and owners alike in maintaining their own vehicles to a high standard. Prepare for a visual journey, as we delve into the intricate process of revitalizing this Mercedes Benz SL 500.
The detailing process commenced with the interior.
The SL500’s cockpit, while seemingly well-maintained and relatively clean at first glance, was targeted for a deep cleanse and protective treatment. The strategy was to thoroughly purify the dark interior and then fortify all surfaces with a layer of premium protection. After meticulously vacuuming the carpets and floor mats, a solution of Woolite and water was prepared. Using a microfiber towel, every interior surface was carefully wiped down. Experience dictates that even interiors that appear clean, especially in convertibles with dark upholstery, harbor a surprising amount of hidden dirt and contaminants. This proved to be true once again.
Following the initial surface cleaning, attention was directed to the intricate cracks and crevices, ensuring the removal of any lodged debris.
Notice the engine start/stop button elegantly integrated atop the shift knob – a testament to the SL500’s thoughtful design.
Ventilation grilles, often neglected, also received meticulous cleaning.
The driver’s seat, typically bearing the brunt of wear and tear, was no exception, despite the car’s low mileage. The left bolster showed signs of dirt accumulation and dye transfer, likely from denim, necessitating thorough cleaning.
For this task, an all-purpose cleaner (APC) diluted to a 10:1 ratio was employed, gently agitated with a specialized leather brush.
Post-cleaning, the leather surfaces, including the treated driver’s seat and the rest of the interior leather, were conditioned with Optimum Protectant Plus. This UV protectant is favored for its non-greasy, natural-looking finish, preserving the leather’s original appearance rather than imparting an artificial shine.
Door shuts, often overlooked in routine cleaning, had also accumulated their share of dirt, dust, and grime.
These were thoroughly cleaned using Optimum No Rinse (ONR) diluted as a quick detailer (QD) in a spray bottle.
Finally, the pedals, enduring constant contact with footwear and road debris, demanded attention. An APC and a brush were utilized for cleaning, followed by a damp cloth wipe-down to eliminate any residue. Careful product selection is paramount for pedals, ensuring a non-greasy finish for optimal driving safety. Note was taken to address a smudge on the trim above the pedals, demonstrating attention to even the smallest details.
With the interior revitalized, the focus shifted to the exterior of the Mercedes Benz SL 500. The following sections will showcase before-and-after transformations in key areas, illustrating the comprehensive exterior detailing process.
The initial assessment of the SL500’s exterior revealed a significant need for a thorough cleaning. The accumulated dirt and grime were evident, masking the car’s true Aegean Blue Metallic brilliance.
Wheel wells, notorious for collecting road debris, were heavily soiled and presented accessibility challenges.
A notable feature of the SL500 is its height-adjustable suspension, offering three settings. This system is particularly useful for navigating steep inclines without scraping the undercarriage. In this detailing process, the suspension was fully raised. This adjustment provided enhanced access to the wheel wells and the side skirts for polishing, demonstrating the practical benefits of this feature during car care.
Wheel cleaning initiated the exterior detailing phase. The wheels were heavily coated in brake dust and road grime, necessitating a multi-stage cleaning approach.
P21S Wheel Gel was liberally applied to the rims and calipers, working one side of the vehicle at a time, and allowed to dwell. While the wheel gel was working, P21S Total Auto Wash (TAW) was sprayed onto the tires and wheel wells, maximizing cleaning efficiency.
Each wheel and wheel well demanded approximately 10-12 minutes of dedicated cleaning due to the substantial buildup of dirt and brake dust. Brushes were used to ensure thorough cleaning, especially within the wheel well areas.
Upon rinsing, water beading was observed, indicating the presence of existing wax or sealants. These protective layers needed to be removed to ensure optimal polishing performance. Chemical Guys Wash & Clear, at a paint prep dilution ratio of 2oz/gal, was employed to strip these layers. A Gilmour foam gun was used to pre-soak the SL500, followed by a two-bucket wash method, incorporating Chemical Guys Wash & Clear in the wash bucket. Given the heavy contamination, the wash mitt was diligently rinsed in the rinse bucket with a Grit Guard after cleaning each section, preventing reintroduction of dirt and debris to the paint surface.
Following the thorough wash, clay bar treatment was performed using Optimum Instant Detailer as a lubricant. Optimum Instant Detailer was chosen for its slickness, crucial for minimizing marring during the claying process. Both horizontal and vertical surfaces exhibited significant contamination, underscoring the necessity of claying to achieve a smooth surface ready for polishing. This step, while time-consuming, was pivotal in preparing the Mercedes Benz SL 500 for the next stage of detailing.
After claying, a second foam wash was conducted to ensure the surface was completely clean and free of any remaining contaminants, preparing it perfectly for polishing.
As previously noted, the SL500’s paint was largely swirl-free, but it presented random scratches and noticeable water spot etching, particularly on horizontal panels. Menzerna PO203S was selected for a one-step polishing process. This polish is favored for its versatility, offering effective defect correction when paired with appropriate pads, while also delivering a finish ready for last step products (LSP). Multiple IPA wipedowns were performed post-polishing to ensure no fillers or masking agents were interfering with the true finish assessment. A test section confirmed PO203S as the optimal choice for this Mercedes Benz SL 500.
Attention to detail extended to the underside of the side skirts. For these confined areas, a smaller 4-inch white spot buff pad was utilized. An exercise mat provided cushioning on the hard floor for added comfort during the process.
The results after polishing with PO203S, prior to LSP application, showcased the enhanced clarity and corrected paintwork.
The SL500’s glass roof, exhibiting heavy water spotting, was polished using a Porter Cable (PC) polisher with a white polishing pad and Optimum Poli-Seal. Optimum Poli-Seal provides sufficient cut to eliminate water spots while leaving a slick, protective finish expected to last for months.
The Aegean Blue Metallic paint presented a dynamic color, shifting between grey and light blue depending on the light. A macro shot captures the intricate metallic flake within the paint.
Following polishing, an IPA wipedown, followed by an Optimum Instant Detailer wipedown, prepared the finish for sealant application. Optimum Opti-seal was chosen for its ease of application and natural-looking protection, avoiding the artificial sheen sometimes associated with sealants. Its durability was also a key factor, having proven effective through harsh winter conditions.
Application was performed with a red applicator pad, and after curing, the sealant was buffed out with a soft microfiber towel and a light mist of Optimum Instant Detailer.
After sealing, P21S 100% wax was applied by hand using a separate red applicator pad. While not the most durable wax option, P21S 100% wax was selected for its exceptional finish, ease of application and removal, and rapid curing time.
Areas often neglected, such as the underside of the trunk lid above the license plate, were also addressed. This area had accumulated approximately three years of grime.
The transformation after detailing was significant, revealing the clean, pristine surface.
Even the Mercedes emblems showed considerable contamination, beyond simple surface dirt.
Emblems were polished using a PC polisher with a white pad and Menzerna 106FA polish. All-in-one products like Optimum Poli-Seal or Klasse AIO are also effective for emblem polishing.
Before detailing, the Mercedes badge showed signs of grime accumulation.
After polishing, the badge was restored to its original luster.
Exhaust tips were heavily tarnished. Initial cleaning involved P21S TAW and 0000 steel wool, followed by polishing to restore their shine.
The exhaust tips after detailing exhibited a mirror-like finish.
