What are the treatment methods for car chassis rust? The following are the most common methods.
Preliminary treatment of rust
First, lift the car to better treat the rusty parts of the chassis. For surface rust, the rust can be removed by grinding, which is a relatively simple and direct method.
Cleaning the chassis
Use a high-pressure water gun to fully rinse the chassis, then apply the engine external cleaning agent or degreasing agent to thoroughly remove the sludge and sand attached to the chassis. This is the basis for ensuring the subsequent anti-rust treatment effect. Then, use a water gun to blow out the accumulated water in the gap of the chassis, and wipe it clean with a dry towel to keep the surface of the chassis dry to prevent moisture from penetrating into the chassis and causing further damage.
Preparation for anti-rust treatment
Before spraying the anti-rust treatment layer, use masking paper and tape to carefully cover the area around the tires and exhaust pipes to avoid unnecessary impact on these parts that do not require anti-rust treatment.
Spraying anti-rust coating
Spray the chassis anti-rust material evenly on the chassis surface to ensure that the coating has good hiding power, which can prevent the chassis from rusting and improve the durability of the chassis. When performing anti-rust work, try to keep the type of paint used consistent to ensure the effect. Coating uniformity is essential, and a uniform coating can prevent the anti-rust paint from falling off and provide long-lasting protection.
Subsequent cleaning and waiting for air drying
Remove all coverings and use a special cleaner to clean the unsprayed areas around the chassis. Finally, wait for the chassis to air dry naturally to achieve the best effect. Do not drive on the road immediately and wait until it is completely dry before using it.
Choose a suitable treatment site
For deep protection of the chassis, it is crucial to choose a professional and reputable car maintenance center. Small auto repair shops may use low-end materials, and the quality of the spray coating is difficult to guarantee. Therefore, it is recommended to choose a 4S shop or a professional auto repair shop to ensure the effect of the anti-rust treatment.
In addition, chassis rust is often not easy to detect, and regular inspections are the key to preventing chassis rust.
