Is it necessary to apply anti-rust coating on a new car's chassis?
2 Answers
New car chassis do not require anti-rust coating. Here is more information about chassis anti-rust treatment: 1. Functions: (1) Rust and corrosion prevention. Anti-rust coating can effectively isolate contact with moisture and acidic substances in the air, extending the vehicle's service life. (2) Impact resistance. After applying anti-rust coating to the car's underside, even gravel impacting with 300 kg of force won't penetrate it. (3) Improved driving comfort. Chassis anti-rust treatment can eliminate resonance caused by friction between wheels and road surface, significantly reducing interior noise. 2. Service life: Generally 3 years or 60,000 km, or 4 years or 100,000 km. It's recommended to perform chassis anti-rust treatment once a year.
I live in a coastal city where the air is humid and salty. After just one year of driving my new car, rust started appearing on the undercarriage, which made me regret not getting rustproofing done earlier. The factory-applied coating on new cars is too thin to withstand corrosion. Rustproofing is like putting a protective coat on the undercarriage—applying a professional coating can prevent rust for five to ten more years. Especially during rainy seasons or when driving through standing water, metal components are prone to oxidation, which affects the vehicle's overall lifespan. My friend didn’t rustproof his car, and by the third year, he had to spend thousands on undercarriage repairs and part replacements—far more expensive than a few hundred bucks for prevention. In short, getting undercarriage rustproofing done when the car is new is worth it. It saves hassle and money, prevents major repairs down the road, and I recommend choosing a reputable shop for the job—it’ll give you peace of mind while driving.
