BMW 740i Chrome Delete Review — Oxide Gray Blackout Trim

Transforming the BMW 740i: The Art of Chrome Delete

The process of transforming the chrome accents on a BMW 740i into a sleek, black finish, commonly known as 'chrome delete' or 'blackout trim,' is a nuanced task that significantly elevates the vehicle's aesthetic. This modification unifies the exterior chrome elements, imbuing the luxury sedan with a more sophisticated and sporty character. This article details the transformation of an Oxide Grey BMW 740i, including the practicalities of time, cost, and essential aftercare.

Key aspects covered:
1. The necessity and cost considerations of chrome delete.
2. Pre-installation inspection and area verification.
3. Preparation: Disassembly and meticulous masking.
4. The film application process.
5. Achieving a flawless finish.
6. Post-installation appearance and maintenance tips.

Chrome Delete: Replacement vs. Wrapping

There are two primary methods for converting chrome trim to black. The first involves replacing the original chrome parts with black OEM components. However, this approach is considerably expensive and carries the risk of damage during the disassembly of existing parts. The second, and increasingly popular, method is film wrapping, which offers a more flexible and cost-effective solution. For a premium vehicle like the BMW 740i, replacing all chrome elements could run into several million Korean won. In contrast, wrapping allows for variable costs depending on the extent of the coverage, and importantly, the original chrome can be restored if desired. Typically, chrome delete for a sedan ranges from 800,000 to 1.5 million Korean won, but for models like the 7 Series with extensive chrome detailing, the cost can range from 1.5 million to 2.5 million Korean won.

Detailed Inspection of the BMW 740i's Chrome Elements

The specific BMW 740i in this review, finished in Oxide Grey, was slated for a complete chrome delete using black gloss film. The targeted areas included the front grille, window surrounds, lower mirror casings, door handles, and the trim around the taillights and lower rear bumper. The BMW 7 Series features chrome accents distributed across the entire vehicle, necessitating varied application techniques for each section. While some components may require removal, most are wrapped in situ. Consequently, comprehensive masking is crucial to protect the vehicle's paintwork from any potential scratches or damage during the wrapping process.

The Crucial Role of Film Quality

For this transformation, 3M 2080 Series gloss black film was selected. This premium film features a protective layer that minimizes micro-scratches from squeegee application and boasts superior adhesion, greatly reducing the likelihood of lifting or premature peeling. The choice of film significantly impacts the installation's difficulty and the final result. Lower-quality films are prone to bubbling and lifting shortly after application and can fade within one to two years due to UV exposure. High-quality films, however, are designed to maintain their color and gloss for five to seven years or more.

Installation Process:

1. Preparation: Thoroughly clean all chrome surfaces. Carefully remove any trim pieces that require disassembly and meticulously mask off all adjacent painted areas to prevent scratches.
2. Grille Application: Wrap the entire front grille, including the vertical slats, ensuring a uniform black finish. Special attention is paid to the sensor areas, confirming that the film does not impede sensor functionality.
3. Side Profile Wrapping: Apply film to the window trim, lower mirror housings, and door handles. Complex curves and angles require precise film stretching and positioning to avoid wrinkles or air bubbles.
4. Rear Trim Installation: Wrap the chrome accents around the taillights and the lower bumper trim, ensuring clean edges and a seamless look.
5. Finishing Touches: Carefully trim excess film, tuck edges securely, and apply heat to ensure optimal adhesion and a long-lasting finish.

Results and Maintenance

The completed chrome delete on the Oxide Grey BMW 740i resulted in a dramatically enhanced, aggressive stance. The blacked-out trim provides a striking contrast and a cohesive, modern appearance. To maintain this look, regular washing with pH-neutral soaps and avoiding abrasive materials is recommended. Promptly address any minor lifting or damage to preserve the film's integrity and aesthetic appeal.
