Vehicle chassis is one of the components closest to the ground, which absorbs the high temperature of the road during the day and easily absorbs the moisture in the air at night and early morning. In case of rain, snow or sandy road, more corrosive substances will be attached to the chassis. Over time, the material corrosion of vehicle chassis has intensified, which further affects the use of the whole vehicle: steering mechanism damage, oil pan oil leakage, chassis deformation, abnormal noise and so on. Therefore, old drivers often say: "The car is rotten first."

Rust prevention trick 1: clean the body and chassis regularly.

Frequent bathing of vehicles can remove corrosive substances from the body. If you live by the sea, clean the vehicle chassis at least once a month to reduce corrosion. When cleaning the mud on the chassis with a high-pressure water gun, please be sure to clean it. In addition, dust is prevented from blocking the lower edge of the door and the drainage holes in various parts of the door frame to prevent water corrosion.

Anti-rust coup 2: park in a well-ventilated place

Vehicles like a well-ventilated parking environment, and a damp and closed garage damages the health of the chassis, because it is an ideal environment for metal oxidation and corrosion.

Anti-rust coup 3: Try to choose pavement.

All roads lead to Rome. Try to choose the best way. When vehicles run on dirt roads, gravel roads, shallow roads and other sections, the chassis is not only easy to be hit by gravel particles, destroying the protective coating on the surface, but also easy to attach dirt, sewage, plant roots and so on, which will accelerate the corrosion of the chassis. Therefore, you must choose paved roads when driving, and clean the chassis in time after driving on unpaved roads.

Rust prevention trick 4: clean the chassis in time after winter.

Snow on the pavement may contain snow remover, which is corrosive to the chassis. Therefore, the chassis should be cleaned in time after winter, so as to avoid the snow remover from adhering to the chassis surface for a long time and causing corrosion.

Anti-rust trick five: install chassis armor

It is also a good idea to add armor to the chassis. Chassis armor is an elastic protective layer sprayed on the bottom of the car, and its thickness is generally 2-4 mm. Quick-drying and hardening can protect the automobile chassis, and play the roles of scratch prevention, corrosion prevention, bottom mopping prevention, noise reduction and heat preservation.

The above five tricks keep the chassis away from rust.
