This feature showcases a striking SL500 roadster, bathed in Aegean Blue Metallic, boasting 302 horsepower and 339 lb-ft of torque. Equipped with the sought-after AMG Sport Package, this vehicle offers a taste of AMG performance and aesthetics, distinct from the full-fledged AMG SL55. These cars are undeniably beautiful, and settling into the driver’s seat evokes a sense of perfect harmony.
The owner of this particular Benz Sl500 Amg contacted us seeking a comprehensive cleanup for his garage-kept beauty, which, despite its low mileage (only 7,000 miles), needed some attention. Upon inspection, we observed no swirl marks, but the paintwork displayed a collection of scratches and significant water spots, especially on the horizontal surfaces. The exterior was also noticeably dirty, with a substantial accumulation of brake dust on the wheels.
Recognizing that this detail wouldn’t yield the dramatic paint correction before-and-after shots that often captivate viewers, we decided to shift our focus. Our goal was to meticulously document the often-overlooked smaller areas and offer educational insights for enthusiasts aiming to enhance their car care knowledge, especially for those passionate about maintaining their Mercedes-Benz SL500 AMG models.
As is often the case, we became quite enthusiastic with the photography – apologies in advance for the numerous images! We began our detailing journey with the interior.
The cockpit was in generally good condition and relatively clean upon initial inspection. Our strategy for the dark interior was to perform a thorough cleaning followed by applying a protective layer to all surfaces. After vacuuming the carpets and floor mats, we prepared a solution of Woolite and water. We then proceeded to meticulously clean all interior surfaces using a microfiber towel. Experience has taught us that even seemingly clean convertible interiors with dark upholstery, like this Benz SL500 AMG, often harbor a surprising amount of dirt and contaminants. Our assessment proved accurate.
Following the cleaning of the primary surfaces, we diligently addressed all cracks and crevices to eliminate any lingering debris.
The engine start/stop button is conveniently located on top of the shift knob, a notable feature of the Benz SL500 AMG.
Cleaning the air vents:
The driver’s seat’s left bolster is almost invariably the most soiled area, and even with a mere 7,000 miles on the odometer, this Benz SL500 AMG was no exception. It exhibited some dirt accumulation and dye transfer from denim, necessitating a thorough cleaning.
For this task, we employed an all-purpose cleaner (APC) diluted to a 10:1 ratio and gently agitated the area with a dedicated leather brush.
After cleaning, we treated the driver’s seat and all other leather surfaces within the Benz SL500 AMG’s interior with Optimum Protectant Plus. This UV protectant is favored for its non-shiny, non-greasy finish, restoring a like-new appearance rather than an overly “dressed” look.
The door jambs also presented their share of accumulated dirt, dust, and grime:
We meticulously cleaned them using Optimum No Rinse (ONR) diluted as a quick detailer (QD ratio) in a spray bottle.
Lastly, but certainly not least, we turned our attention to the pedals. Pedals endure constant contact with dirty footwear, making them a key area requiring detailing. We used an APC and a brush for cleaning, followed by wiping with a damp cloth to eliminate any residue. It’s crucial to select pedal cleaning products carefully, avoiding greasy or slippery finishes that could compromise driving safety. (Note: We did address the smudge on the trim just above the pedals!).
With the interior revitalized, we shifted our focus to the exterior of this magnificent Benz SL500 AMG. For certain areas of the car, we captured compelling before-and-after photos, so the following section might jump between different stages of the exterior detailing process.
The images below clearly illustrate that this Benz was in dire need of a comprehensive and thorough exterior cleaning!
The wheel wells were heavily soiled and challenging to access effectively:
Here, a notable feature of the SL500 becomes apparent. It is equipped with a height-adjustable suspension system (offering 3 settings). This can be raised when navigating steep driveways or inclines to prevent scraping the undercarriage. We utilized this feature to its maximum height setting, providing improved access to the wheel wells and side skirts during the polishing phase for this Benz SL500 AMG.
As always, we initiated the exterior detailing by cleaning the wheels. As the image reveals, we faced a significant task.
We began by spraying P21S Wheel Gel onto the rims and calipers (working on one side of the Benz SL500 AMG at a time) and allowing it to dwell for a few minutes to effectively loosen the brake dust and grime. While the wheel gel was working, we applied P21S Total Auto Wash (TAW) to the tires and wheel wells.
The wheels were thoroughly cleaned, utilizing a brush to access and scrub within the wheel well areas. Each wheel and wheel well demanded approximately 10-12 minutes of dedicated cleaning due to the substantial buildup of dirt and brake dust on this Benz SL500 AMG.
Following the initial rinse, we observed water beading, indicating the presence of existing wax and/or sealants. These pre-existing protective layers needed to be removed prior to polishing, as they can interfere with the polishing process. To aid in stripping these layers, we used Chemical Guys Wash & Clear at a paint prep ratio (2oz/gallon). We employed our Gilmour foam gun to pre-soak the Benz SL500 AMG, and then prepared our two buckets, one of which also contained CGWC. Given the car’s heavy contamination, we meticulously cleaned our wash mitt in the rinse bucket with a Grit Guard after each small section to prevent reintroducing dirt and debris onto the paint surface.
After a comprehensive wash, we proceeded to clay bar the Benz SL500 AMG using Optimum Instant Detailer (a very slick product) as a clay lubricant. Using a high-quality lubricant during claying is paramount to prevent marring the paint surface. We discovered significant contamination on both horizontal and vertical surfaces, indicating a strong need for claying. While this process was time-consuming in achieving a smooth surface ready for polishing, it yielded a substantial improvement once completed.
Due to the extensive contamination removed during claying, we opted to foam wash the Benz SL500 AMG once more to ensure the surface was exceptionally clean and fully prepared for the polishing stage.
As mentioned earlier, the paintwork was largely free of swirl marks, but it exhibited numerous random scratches and considerable water spot etching, particularly on the horizontal panels of this Benz SL500 AMG. Our chosen approach was to utilize Menzerna PO203 for a one-step polishing process. We have increasingly favored this versatile polish, finding it highly effective. When paired with the appropriate pad, it delivers a noticeable level of cut while also achieving a finish ready for a last step product (LSP). However, we always recommend performing several IPA wipedowns afterward to confirm the absence of any fillers or masking effects. Following our standard test section, we confirmed that PO203 was the ideal solution for this Benz SL500 AMG.
Attention to detail extends to often-overlooked areas like the underside of the side skirts of the Benz SL500 AMG. For these confined spaces, we switched to a smaller 4” white spot buff pad. We also utilize an exercise mat to cushion the hard floor, enhancing comfort during lower section work!

The glass roof displayed heavy water spotting, prompting us to polish it using a Porter Cable polisher (PC). We used a white polishing pad and Optimum Poli-Seal. This combination provides sufficient cutting power to clean the glass effectively while leaving behind a very slick finish and durable protection for months to come on this Benz SL500 AMG.
The Aegean Blue Metallic paint is a captivating color, shifting in appearance from grey to light blue depending on the lighting conditions. Here’s a macro shot revealing the intricate metallic flake within the paint of this Benz SL500 AMG.
With polishing complete, we performed an IPA wipedown followed by an Optimum Instant Detailer wipedown. Now, the finish of the Benz SL500 AMG was perfectly prepared to be sealed with Optimum Opti-seal. This is our preferred product for paint protection due to its ease of application and its natural look, avoiding the artificial, plastic-like sheen sometimes associated with other sealants. It has proven highly durable on our own vehicles, even through harsh Midwest winters, reinforcing our confidence in its longevity.
We applied Opti-seal using a red applicator pad and, after allowing it to cure, buffed it to a perfect shine using a soft microfiber towel and a light mist of Optimum Instant Detailer on this Benz SL500 AMG.
Following the sealant application, we hand-applied P21S 100% wax using a separate red applicator pad. While not the most durable wax available, P21S 100% delivers an exceptionally pleasing finish. It is easy to apply and equally quick to remove, with minimal curing time required. As soon as we finished applying it to the entire Benz SL500 AMG, we immediately began the removal process.
Here’s an area that frequently escapes attention: the underside of the trunk lid, directly above the license plate on the Benz SL500 AMG. As you can see, approximately three years’ worth of grime had accumulated in this area.
After detailing:
Even the emblems presented significant challenges. This wasn’t just superficial dirt removable with a simple wash on this Benz SL500 AMG.
We polished the emblems using a Porter Cable polisher with a white pad and Menzerna 106FA polish. (Alternatively, all-in-one products like Optimum Poli-Seal or Klasse AIO also work effectively on emblems).
