Is Undercoating Necessary for Sedans?
2 Answers
Undercoating is necessary for sedans. The reasons for applying undercoating to sedans and the functions of a car's chassis are as follows: Reasons for applying undercoating to sedans: Undercoating is non-toxic, provides high coverage, and has strong adhesion. It can be sprayed on exposed areas such as the vehicle's undercarriage, wheel hubs, fuel tank, lower body panels, and trunk. After quick drying, it forms a durable elastic protective layer that prevents impacts from flying stones and gravel, avoids moisture, acid rain, and salt from corroding the metal parts of the undercarriage, prevents rust and corrosion, and ensures the safety of the driver. Functions of a car's chassis: The car chassis consists of four parts: the transmission system, running gear, steering system, and braking system. The chassis supports and mounts the car engine and its components, forms the overall shape of the car, receives the engine's power to enable movement, and ensures normal driving.
To be honest, as a frequent long-distance driver, I personally believe vehicle armor is genuinely necessary in certain situations, such as working in high-crime areas or potentially threatening environments. Armor provides bullet and impact protection, but it's absolutely unnecessary for ordinary urban life. The costs are too high - armor modification starts at several hundred thousand yuan, daily maintenance is troublesome, the added weight makes handling difficult, and fuel consumption increases by 10%-15%. A more practical approach is investing in intelligent safety systems like automatic braking and reducing risks through driving training. In reality, safety relies more on anticipation - armor is just a psychological comfort tool. Don't blindly follow trends; assess your actual situation before deciding.
