Is it necessary to apply undercoating to a car?
2 Answers
Applying undercoating to a car is necessary as it provides better protection for the vehicle's chassis and offers some sound insulation. Undercoating is not actually armor, but rather a high-tech adhesive rubber asphalt coating applied to the car's chassis, typically 2mm to 4mm thick. The benefits of undercoating include: 1. Anti-corrosion: It effectively resists corrosion from sewage, oil stains, and other contaminants on chassis components, extending their service life; 2. Anti-friction: Undercoating can withstand minor undercarriage scrapes and reduce the impact and friction from small stones and debris kicked up during high-speed driving; 3. Noise reduction: Due to its rubber asphalt composition and certain thickness, undercoating can to some extent isolate noise transmitted from the chassis.
I believe underbody armor is quite necessary, especially if you live in rainy and salty areas like the northeast or coastal regions. I feel much more at ease after installing underbody armor on my own car—it effectively prevents rust and scratches, providing an extra protective layer for metal components underneath the vehicle. Installing it during the new car phase can avoid rust issues later and extend the overall lifespan. For example, in northern winters where salt is spread to prevent ice, the salt can rapidly corrode the undercarriage, but armor blocks these elements and saves on repair costs. The cost ranges from a few hundred to around a thousand yuan, which isn’t high, and this investment is far more cost-effective than major repairs. In the long run, it improves the car’s durability and is worth considering for new cars or off-road vehicles.
