It is necessary to apply undercoating to a car. After quick drying, the undercoating forms a firm elastic protective layer that can prevent impacts from flying stones and gravel, avoid moisture, acid rain, and salt from corroding the metal parts of the vehicle's undercarriage, prevent rust and corrosion of the chassis, and protect the driving safety of the car owner. Relevant information about undercoating is as follows: 1. Introduction: The formal name of automotive undercoating is automotive chassis anti-collision, anti-rust, and soundproof coating ("UNDERCOATING" primer), a high-tech adhesive rubber asphalt coating. It is non-toxic, with high coverage and adhesion. 2. Function: After quick drying, it forms a firm elastic protective layer that can prevent impacts from flying stones and gravel, avoid moisture, acid rain, and salt from corroding the metal parts of the vehicle's undercarriage, prevent rust and corrosion of the chassis, and protect the driving safety of the car owner.
I just entered society and bought a new car, and I’ve been wondering whether undercoating is worth it. As a working professional who mainly commutes in the city, the road conditions are quite smooth, and there isn’t much rain, so I initially skipped it. Later, I took a long trip to visit relatives in the countryside, encountered bumpy dirt roads, and had some scratches on the undercarriage from flying stones—repairs cost me a few hundred bucks, and I regretted it afterward. Now, thinking back, undercoating is just a protective coating that prevents rust and corrosion, especially useful in humid or high-salt areas. But if you drive mostly in dry urban areas, the factory-applied basic coating might suffice. I checked the price—usually around 500 to 800 RMB, not too expensive, but it can extend the car’s lifespan. Before my next car purchase, I’ll definitely get it done in advance, at least for peace of mind. My advice is to decide based on your driving habits and environment—don’t wait until problems arise like I did. Consulting a professional shop is the most reliable; they can assess your car’s condition.
