It needs treatment. The methods for treating rust on a car chassis are as follows: 1. Regularly clean the car chassis: Pay special attention to cleaning the car chassis. Due to varying road conditions, it's difficult to ensure the vehicle remains clean after some use. The car's chassis is the most exposed part to road contaminants like sewage. Therefore, when washing the car, try to pay more attention to cleaning the chassis. 2. Rust removal: Directly polish it and choose some high-quality rust-proof and waterproof coatings for repair. Regular maintenance requires frequent inspections. When performing rust-proofing work on the car, it's important to use the same type of paint for the best results. 3. Perform rust-proof treatment on the chassis: Visit a 4S shop or a more professional auto repair shop for treatment. Only then can outstanding results be achieved. During the rust-proof treatment process, the uniformity of the coating is extremely critical. A uniform coating will prevent the rust-proof paint from peeling off, while an uneven coating will lead to large areas of rust-proof paint falling off, rendering the maintenance ineffective. Note that after applying the rust-proof material, the car should not be driven immediately. It must be naturally air-dried to achieve better results.

I have some experience in car repair and believe that rust on the chassis must be addressed, otherwise it can be quite dangerous. The chassis is the skeleton of the car, and rust can make the metal brittle. If you hit a big bump while driving, it might crack and cause an accident. I once had a car with chassis rust that I ignored, and it ended up making severe noises when driving on mountain roads in winter—later requiring expensive major repairs. Fixing it isn’t too complicated: first, remove the rust with sandpaper or a wire brush, then apply anti-rust paint, or take it to a professional shop for an undercoating treatment. Daily prevention is also crucial—like avoiding parking in damp areas and checking before the rainy season. Delaying repairs will only make the rust worse, increase repair costs, and may even affect suspension components. In short, safety comes first—don’t risk big problems to save small costs.

Buddy, I've personally experienced car chassis rusting, and you really can't afford to delay dealing with it! At first, I didn't pay much attention to the rust spots on my old car's chassis, but they spread over time. When I went to fix it, I found that the steering system was already affected, costing me several hundred bucks. The solution isn't hard: just clean the rust spots thoroughly and spray some rust inhibitor, which you can easily find at any hardware store. Make sure to check regularly, especially if you park outdoors or in areas with salted roads, as rust can accelerate there. If there's too much rust, it's better to have a professional handle it for peace of mind. Leaving it untreated long-term can weaken the chassis structure and compromise driving safety. Spending a little money to fix it early saves you a lot of trouble down the road.

Rust on the chassis indeed needs to be addressed. It not only affects appearance but also corrodes the metal structure, reducing the vehicle's lifespan. Simple solution: clean the chassis, remove rust, and apply anti-rust paint for prevention. If the rust is severe, seek professional repair at a maintenance shop. Ignoring this issue allows rust to spread, damaging suspension or braking components, leading to safety hazards. Regular inspections in daily use can prevent problems before they occur.
