The Model 210 4-MATIC is produced in the Graz plant.
The following chart shows the corrosion protection measures in the Graz plant, starting with cleaning the body-in-white through to assembly of the now painted and protected body.
The paint structure is shown on the example of an engine hood.
The temperatures specified relate to the target temperature of the bodies.
