This stunning SL500 roadster, finished in Aegean Blue Metallic, boasts 302 horsepower and 339 lb-ft of torque, further enhanced by the AMG Sport Package. While not the full-fledged AMG SL55, this Benz Sl500 is undeniably a remarkable vehicle. Slipping into the driver’s seat evokes a feeling of perfect harmony, where everything simply feels “right”.
The owner, a discerning enthusiast, contacted me to revitalize his cherished Mercedes-Benz SL500, which, despite its low mileage (a mere 7,000 miles), spends considerable time garaged and was in need of a comprehensive clean-up. Upon inspection, it was evident that swirl marks were minimal, but the paintwork presented a collection of scratches and significant water spots, particularly on horizontal surfaces. The exterior was also noticeably soiled, with a substantial accumulation of brake dust encrusting the wheels.
Recognizing that this Benz SL500 wouldn’t offer the dramatic paint correction transformations often showcased, I decided to shift focus. My aim was to meticulously document the frequently overlooked smaller details and transform this detailing session into an educational experience for fellow car care enthusiasts eager to enhance their own vehicles.
As is often the case, I became engrossed in capturing the process through photographs – apologies in advance for the extensive image collection! The interior was the initial focus.
The cockpit of the SL500 was in reasonably good condition, appearing relatively clean at first glance. My strategy for the dark interior was a thorough cleaning followed by the application of surface protection. After vacuuming the carpets and floor mats, I prepared a solution of Woolite and water, and proceeded to meticulously clean all surfaces using a microfiber towel. Experience has taught me that even seemingly clean convertible interiors, especially dark ones, harbor a surprising amount of dirt and contaminants. This proved to be true once again.
Following the initial surface cleaning, I meticulously addressed all cracks and crevices to eliminate any lingering debris.

Cleaning the air vents:

The driver’s seat, particularly the left bolster, consistently accumulates the most grime. Even with only 7,000 miles, this Benz SL500 was no exception. It exhibited dirt accumulation and dye transfer from denim, requiring careful attention.
Alt text: Before cleaning, showing a visibly dirty leather driver’s seat in a Mercedes-Benz SL500 convertible.
For this, I employed an All-Purpose Cleaner (APC) diluted to a 10:1 ratio, gently agitating the area with a dedicated leather brush.
After cleaning, I treated the leather (and all other leather surfaces within the interior) with Optimum Protectant Plus. This exceptional UV protectant leaves a natural, non-greasy finish, restoring the leather’s appearance to a like-new condition rather than an artificially “dressed” look.

The door shuts also presented a build-up of dirt, dust, and grime:

Lastly, the pedals often endure significant wear and tear from dirty footwear, thus requiring attention. For pedal cleaning, I utilize APC and a brush, followed by wiping down with a damp cloth to eliminate any residue. It’s crucial to select cleaning products carefully for pedals, avoiding greasy or slippery finishes that could compromise driving safety. (And yes, I did address that smudge on the trim above the pedals!).

With the interior revitalized, attention shifted to the exterior of the Benz SL500. For certain areas, I captured compelling before-and-after photographs, so the following section might transition between different stages of the exterior detailing process.
The images below clearly illustrate that this Mercedes-Benz SL500 was in dire need of a comprehensive and thorough exterior cleaning!

The wheel wells were particularly grimy and challenging to access:

Here, a notable feature of the SL500 becomes apparent: its height-adjustable suspension (offering 3 settings). This system can be raised when navigating steep inclines, preventing scraping. In this instance, I fully raised the suspension to enhance accessibility to the wheel wells and side skirts during polishing.

As always, wheel cleaning is the initial step in exterior detailing. As you can see, significant effort was required.
Alt text: Severely dirty wheels and tires of the Mercedes-Benz SL500 before the wheel cleaning process.
First, I applied P21S wheel gel to the rims and calipers (working on one side of the car at a time) and allowed it to dwell for several minutes. While the wheel gel was working, I sprayed the tires and wheel wells with P21S Total Auto Wash (TAW).

The wheels were meticulously cleaned, and a brush was employed to scrub inside the wheel well areas. Each wheel and wheel well required approximately 10-12 minutes of dedicated cleaning due to the heavy accumulation of dirt and brake dust.

Following rinsing, I observed water beading, indicating the presence of existing wax and/or sealants. These protective layers needed to be removed prior to polishing, as they can impede the polishing process. To facilitate this removal, I used Chemical Guys Wash & Clear at a paint-prep dilution ratio (2oz/gallon). I utilized my Gilmour foam gun to pre-soak the Benz SL500, and then prepared my two buckets, one of which also contained Chemical Guys Wash & Clear. Given the significant contamination, I diligently cleaned my 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, I proceeded to clay bar the Mercedes-Benz SL500, using Optimum Instant Detailer (an exceptionally slick product!) as a clay lubricant. Employing a high-quality lubricant during clay bar treatment is essential to prevent marring the paint surface. I found significant contamination on both horizontal and vertical panels, underscoring the necessity of claying. While time-consuming, this step was crucial in achieving a smooth surface, properly prepared for polishing, and yielded a substantial improvement.
Due to the extensive contamination removed during claying, I opted to foam wash the SL500 once more to ensure a pristine, squeaky-clean surface, fully prepared for the polishing stage.

As mentioned earlier, the paintwork was largely swirl-free, but exhibited numerous random scratches and significant water spot etching, especially on horizontal surfaces. My strategy was to utilize Menzerna PO203 for a one-step polishing process. I have increasingly favored this versatile polish, finding it capable of delivering effective cut when paired with appropriate pads, while also achieving a Last Step Product (LSP)-ready finish. However, I recommend several IPA (Isopropyl Alcohol) wipedowns afterward to confirm the absence of fillers or masking effects. Following my standard test section, PO203 proved to be the optimal choice for this Benz SL500.

Don’t overlook the undersides of the side skirts – a testament to the definition of “detailing”. For these confined areas, I switched to a smaller 4-inch white spot buff pad. An exercise mat provides cushioning against the hard floor!

The glass roof exhibited significant water spotting, prompting me to polish it with a Porter Cable (PC) polisher. I used a white polishing pad and Optimum Poli-Seal. This combination offers sufficient cutting power to clean the glass, while leaving behind a remarkably slick finish and providing months of protection concurrently.

This Aegean Blue Metallic paint is truly captivating. Its appearance shifts – sometimes appearing grey, other times light blue. This macro shot reveals the intricate metallic flake within the paint.

With polishing complete, I performed an IPA wipedown, followed by a wipedown using Optimum Instant Detailer. The finish was now prepared for sealing with Optimum Opti-seal. Opti-seal is my preferred protection product due to its ease of application and natural appearance, avoiding the artificial “plastic-like” sheen of some sealants. Its durability proved exceptional, enduring the harsh Midwest winter on my personal vehicles, further reinforcing my preference for its longevity.
Application is performed using a red applicator pad, and after curing, I buff the sealant using a plush microfiber towel and a light mist of Optimum Instant Detailer.
Following sealant application, I applied P21S 100% wax by hand using a separate red applicator pad. While not the most durable wax available, P21S 100% wax imparts a stunning finish. It applies effortlessly, and removal is equally swift. It also requires minimal curing time – as soon as I finish applying it to the entire Benz SL500, I immediately commence the removal process.
Here’s a commonly neglected area: the underside of the trunk lid, directly above the license plate. As evident, approximately three years of accumulated grime resided here.
