2021 Mercedes-Benz AMG GT Paint Protection Film Damage

Symptoms of Paint Protection Film Issues

Owners of a 2021 Mercedes-Benz AMG GT may observe "Damage or discoloration to paint protection films on vehicle." This can manifest as various forms of "Paint damage" or "Paint/corrosion" that are often attributed to "Environmental influences." These issues specifically affect the protective film applied to the vehicle's paint, compromising its appearance and protective qualities.

Important Warnings for Owners

Mercedes-Benz states that "Chip protection films are a wear item that may need to be replaced over the life of the vehicle." It is crucial for owners to understand that these films "are typically not covered by vehicle warranty." This means that any replacement or repair due to wear and tear, damage, or discoloration of the Mercedes-Benz AMG GT paint protection film will likely be at the owner's expense.

Repair Procedure Summary: Proper Application of Paint Protection Film

This technical service bulletin outlines an 8-step procedure for the proper application of new paint protection films, which can resolve issues like damage or discoloration. The process emphasizes meticulous surface preparation and careful film handling to ensure a durable and aesthetically pleasing finish for your Mercedes-Benz AMG GT paint protection film.

1. Prepare the Solution: Technicians must first prepare a specific 0.2% soap solution by mixing 1,000ml of water with 2ml of liquid soap. This solution is critical for both surface wetting and protecting the adhesive during application.
2. Clean the Surface: The vehicle's paint surface where the film will be applied must be thoroughly cleaned to ensure it is dust-free. Any contaminants can compromise adhesion and appearance.
3. Assisted Cleaning: For enhanced cleaning, isopropyl alcohol (rubbing alcohol) can be used to remove stubborn residues. A lint-free rag is highly recommended for a final secondary dusting to eliminate any remaining particles before film application.
4. Wet Hands: Before handling the film, technicians should wet their hands with the prepared soapy water solution. This prevents contamination from oils or dirt and protects the delicate adhesive surface of the film.
5. Remove Backing Paper: The backing paper must be completely removed from the paint protection film, exposing the adhesive side.
6. Moisten Vehicle and Film: The vehicle surface is thoroughly moistened with the soapy water. The protective film can then be laid with its adhesive side out onto the wetted surface, ensuring the adhesive layer is also fully covered in the soapy water solution. This allows for repositioning.
7. Position and Squeegee: The film is gently placed adhesive side down onto the paint surface, aligning it correctly. Working from the center outwards, a squeegee is used to press the soapy water solution from under the film. Sufficient pressure is applied to firmly adhere the film to the paint surface without causing damage or stretching the material.
8. Curing: The newly applied film and paint must be allowed to "cure" until all moisture has completely evaporated. The adhesive needs to dry and cure sufficiently to ensure a strong, lasting bond before the vehicle is released for use.
