Even completely galvanised car bodies are susceptible to corrosion. Her appearance is a matter of time. The worst of the rust is the wheel arches (wings), the luggage door or the trunk lid and the bonnet leading edge. These places rust faster than others because they are more engaged with aggressive compounds, such as reagents and fuels and lubricants.
The corrosion of the new car starts much earlier than its tracks appear on the surface of the body. As a rule, the body of a modern European car is capable of withstanding cross-corrosion of 10-12 years.
In fact, the length of service of the body is highly dependent on the operating conditions. For example, in a region where heavy frosts prevail, the body will last longer than in the humid climate or in the seaside territories.
The rust is most likely to appear at the place of education of the bevels, which is why it is desirable to renovate recently on the paint coatings. Especially if it's metal.
Also, rust may appear due to the technology violation during the processing and painting of the body. In this case, the part is subject to warranty repair.
Unfortunately, if the rust has appeared, it won't be able to get rid of it forever. She'll be back in time. In order for the rust to be repaired after the repair of the body, some are glued to the repaired details of the special, transparent protective film. These films are hardly visible and well protected. Alternatively, a protective polishing of "liquid glass" that creates an invisible protective layer on the surface of the LCP can be used.
