Is it normal for Volkswagen's cavity wax to leak out?

[Lauren]

It is normal for Volkswagen's cavity wax to leak out, as this indicates that the car's cavity wax injection process is qualified. The following is an introduction to cavity wax injection: 1. Introduction to cavity wax injection: A certain amount of liquid wax is injected into the four cavities at the bottom of the car body. Through a specific process, the wax remaining inside the car body cavities forms a uniform protective wax film, preventing water droplets from entering and ensuring excellent anti-corrosion performance for the entire vehicle. 2. Material aspect: As long as steel materials are used, rust will occur. Galvanized steel sheets cannot completely prevent rust. When manufacturing components with cavities, wax injection holes are usually pre-drilled. Some enclosed areas will have holes to facilitate the outflow of liquid wax during the wax draining process in the wax draining room.
