The M4 Coupe is BMW’s latest adrenaline fuelled offering, replacing the M3 as their 2 door performance car for those looking for the unique M Sport thrill. At just under 1500kg it’s incredibly light, giving the brand new 431hp M ‘TwinPower’ Turbo straight six-cylinder petrol engine the opportunity to propel it from 0-62mph in around 4.2 seconds. To achieve the weight in spite of the increased length, BMW constructed the driveshaft from carbon fibre, hollow half shafts, carbon fibre roof and output shaft, aluminium bonnet, wings and suspension components and a composite tailgate. For additional weight saving, the turbo is achieved by combining the power from two small single-scroll turbo chargers keep the weight down, keep engine emissions low whilst providing enough torque on tap to eliminate the usual associated lag. The sound of the engine pumped through the speakers into the cabin helps to keep heartbeats racing!
This brand new BMW M4 arrived at Ultimate Detailing Studio having been collected from the dealership in preparation for New Car Protection Treatment. The initial inspection revealed a sticky residue from the protective transportation wax that had attracted a fair amount of driving debris and environmental fallout. This would need to be addressed before work could commence.
The first step was to apply Nanolex Wheel Cleaner & Iron Remover to the bodywork and wheels. This acts on ferrous contamination which may have been collected in transit from the factory to the dealership, or from the brake pads shredding whilst under pressure. Wheel Cleaner & Iron Remover changes colour to a deep purple on contact with iron particles, shrinking them to break the bond with the underlying substrate and allowing them to be freely rinsed away.
I use a Kranzle 1152 TST Pressure Washer to rinse away all traces of the product and to give the underside of the wheel arches a really good blast to remove any debris that may have accumulated under there. – Derek Ginger, Master Detailer, UDS
Next the M4 was treated with Valet Pro Citrus Tar & Glue Remover to dissolve any remaining residue of transportation wax. Then Ultimate Snow Foam was applied to remove the larger particles of dirt and grit. The high-foaming nature of the product allows it to get under the contamination, lifting it away from the surface of the paintwork and trapping it within the foam. This can then be rinsed away without endangering the paintwork with unnecessary contact. This type of non-contact pre-cleaner helps prevent the introduction of scratches and swirls during the wash process, yet is a commonly omitted step with many car dealerships.
Finally the M4 was washed using the Two Bucket Method, an Ulti-Mitt Double Sided Merino Wash Mitt and Nanolex Pure Shampoo. Once the suds were rinsed away the M4 was given a final, pure water rinse using an Aqua Gleam De-ionising water filter. This filter neutralises the impurities in tap water associated with white water spot deposits. Using soft towels the M4 was dried and brought into the detailing studio for close inspection under high intensity lighting.
The 3M Sun Gun revealed buffer trails down one side of the car. Someone had clearly attempted to remove imperfections from the panels but they’d used an overly aggressive pad and compound combination and then failed to refine it. The result was this unusual smeared, glazing effect. – Derek Ginger, Master Detailer, UDS
To remove the buffer trails a FLEX PE14-2-150 Rotary Machine Polisher was used, with SCHOLL Concepts S17+ High Performance Compound on a Flexipads Coolshine Red Polishing Pad. The paintwork was then refined using SCHOLL Concepts S40 Anti-Swirl Compound and a Flexipads Soft-Buff Black Finishing Pad to leave a perfect, high gloss finish.
To prepare the paintwork and wheels for the sealant layers they were first cleansed using Nanolex EX Residue Remover. This ensures the substrate is completely free from oils, fillers, polish residues and silicones and will allow the sealant to bond directly to the underlying substrate. This makes it stronger and more durable. Then to protect the finish Nanolex Si3D was applied.
Si3D is the latest in the range of Nanolex nanotechnology-based sealants and is composed of silica, nitrogen, hydrogen and organic compounds to form a hydrophobic, flexible cross-linked protective matrix on the treated surface.
We called the new sealant Nanolex Si3D because the particles actually form a 3D network on the surface of the treated substrate once the solvents evaporate. This makes Si3D thicker than similar nanotechnology-based coatings giving it a more defined three dimensional form. – Florian Kessler, Managing Director, Nanolex Car Care
Si3D can be layered to offer up to 9H of protective hardness to clearcoat lacquers. 90% of the contained solvent flashes off within the first 24 hours of application, so the coating cures quickly. The remaining 10% evaporates within a week to leave a fully cured, tough and durable layer, resistant to strong acids and alkaline cleaners. Treated surfaces become incredibly slick to the touch, repelling dirt and contamination and making the weekly wash process easier and safer.
Si3D provides a great level of shine and reflectivity – particularly on this fairly dark colour! The sealant actually deepens the natural paint pigments, so the colour becomes even deeper and glossier. – Derek Ginger, Master Detailer, UDS
The diamond cut wheels were protected using Nanolex Si3D and the glass was sealed using Nanolex Urban Glass Sealant which forms a clear, hydrophobic protective barrier over windows, encouraging rain water to bead and blow away when driving at lower speeds.
The final result was a glossy, sleek finish with a mirror-like shine. When the customer collected his M4 he couldn’t believe it was the same car, remarking on the reflectivity and the enhanced colour brought out by the Si3D. With careful maintenance he should remain impressed for a long time to come!
