Porsche 911 991 Carrera 4S – Paint Correction, Ceramic Coating and Interior Deep Clean
Jet Black Metallic is a colour that rewards effort – and on a 911 Carrera 4S, it delivers presence when properly maintained. This example came in for our Ceramic1 treatment, combined with trim restoration, defect correction, and a full interior revival. Across two days of meticulous detailing, every surface was addressed and elevated to meet the BH Automotive Detailing standard.
Exterior Preparation & Ceramic1 Protection
This vehicle underwent our full Ceramic1 service, which includes a safe wash, chemical decontamination and a single-stage machine polish to remove light swirling and restore clarity.
During the paint depth inspection and visual inspection it became clear the bonnet and front bumper had been re-sprayed. Extra care and effort was given to ensure the finish of these areas matched the rest of the car and enhanced the finish that the bodyshop had achieved.
Following correction, we applied a 1-year ceramic coating, designed to:
Lock in gloss and reflectivity
Improve water behaviour and resistance to road grime
Offer practical, durable protection for everyday use
Detailing Work Completed:
✅ Trim restoration with UV protection to prevent fading and maintain sharp contrast across the vehicle’s exterior
✅ Stone chip correction – colour-matched touch-ins around the front wheel arches, ensuring a seamless finish on high-impact zones
✅ Exhaust polishing to remove tarnish and restore the signature Porsche finish
✅ Silica scale removal from badges and trims, commonly caused by hard water residue
✅ Glass compounded, chemically decontaminated, and coated – focused on the windscreen, panoramic roof and rear screen, improving visibility and ease of cleaning
Interior Deep Clean & Leather Hydration
Inside, the cabin received a full interior deep clean, including:
Steam cleaning of carpets and mats to remove embedded dirt and refresh texture
Leather surfaces rehydrated to maintain suppleness and reduce future wear
All interior plastics and trim cleaned using safe, non-gloss finishes
Even the vehicle key was carefully cleaned and restored to match the overall standard
Client Aftercare Support
To ensure the long-term results of this work, the client was provided with a tailored maintenance care guide to support their personal wash routine. This included:
Safe wash techniques suited to ceramic-coated vehicles
Product recommendations that align with the coating installed
Access to exclusive discounts on approved detailing products
This helps protect their investment while maintaining the BH Automotive Detailing finish between professional visits.
Time Taken: Two Days On Site
Every part of this detail was carried out over two full working days, ensuring no area was rushed and every product had appropriate curing time. The finished result was a Jet Black Metallic 911 that looked deep, sharp, and properly protected.
Final Result
With ceramic protection in place, trim and glass restored, and the interior revived, this Porsche is now set for the road – presenting as it should, and easy to maintain.
