Many years ago, cars were prone to rusting due to poor rust prevention techniques and poor materials used on the body. In recent years, cars have basically had this problem. A car that is in normal use and well maintained will not rust even after more than a decade of use. Of course, if the driving conditions are not good and maintenance is not appropriate, premature rusting may also occur. From the perspective of the entire vehicle, the earliest areas of rust are indeed the chassis components of the vehicle, including the lower door sill. Because various exterior components, such as doors, hood, fenders, etc., if there is paint scraping off, most people will go to touch up the paint, otherwise it will greatly affect the appearance. One of the major functions of paint is to prevent rust, and once repainted, rust will not regenerate. If metal components are exposed on the chassis, many people will not be able to see them first. Secondly, even if the paint falls off, they will not handle it because it does not affect the appearance or appearance temporarily. Gradually, it will rust and become more and more serious.

   So the chassis will rust, does it need to be treated with rust prevention? It depends on the condition of the road being driven. It's best to take mountain roads or roads with a lot of sand and gravel frequently. Any car has undergone rust prevention treatment before leaving the factory. When driving on general roads, the chassis is not bumped and will not rust. If the chassis rusts, it must be because the rust prevention layer has been damaged, exposing the metal components inside. If the owner does not handle it, it will rust over time. The damage to the rust prevention layer is caused by the sand and stones that are pressed against the bottom or the wheels hitting the bottom plate. Therefore, it is recommended to do it when driving on uneven roads, mountain roads, or gravel roads. Driving on such roads has a higher probability of chassis injury. It is not necessary to drive on general roads as long as the chassis is not damaged. If the air pollution in the local area is severe, there is more acid rain, or vehicles are often parked in damp places, it is also recommended to do it. In this environment, it is also very easy to cause rust on the chassis, and doing rust prevention treatment would be safer.

    The anti rust treatment method for the chassis is actually to make chassis armor. When buying a new car, some 4S stores will give it away, while others will suggest that the car owner spend money to purchase, and the price is not too expensive. The method is very simple, which is to spray a layer of adhesive similar to lumps on the chassis, which can prevent rust and also isolate some noise. It is soft, and even stones can play a cushioning role on the chassis, so the metal inside will not be injured, and the effect is still quite significant.

       The materials and craftsmanship of a car chassis can also determine the timing of its rusting. Vehicles with poor materials will rust earlier. The higher the quality of the vehicle, the better the materials and craftsmanship, and the lower the probability of rusting. However, the materials used in cars nowadays, even very cheap ones, are basically not a problem, and they will not rust after more than ten years of normal use. In use, if there is a base, the metal will definitely be exposed. You can go to a 4S store for rust prevention treatment. If there is no support and there are signs of large-scale rust, it is necessary to handle it. First, polish the rust, and then do the chassis armor. If the chassis rusts severely, it will affect its strength, and the safety of passengers in the car cannot be well guaranteed after being heavily impacted.
