The entire surface of the bottom, including the cavities under the rear wings, is covered with a layer of polyvinyl chloride protection. Particularly exposed areas under the front wings are protected from stone impacts by mudguards, all cavities are covered with a special paste. In addition, individual body parts are made of galvanized iron. Before winter and after washing the bottom, the condition of the protective layer should be checked and preserved using a paste for preserving the bottom.

In places exposed to sand and rocks, dirt, clay and sand can accumulate. It is especially important to remove this dirt, which contains a lot of salt, especially in winter. If this dirt is not completely removed, there is a risk that it will not dry out. This can lead to through rust, which will appear on the outside, which over time will be impossible to stop with any anti-corrosion agents.
