Is it necessary to apply undercoating to a car?

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.

I've been driving for twenty years and loved tinkering with cars since my youth, so I've got some experience with undercoating. I remember my first car didn't have undercoating, and the chassis rusted badly during the rainy seasons in the south—cost me over a thousand yuan to repair, which hurt. Nowadays, I get this protective coating done on all my new cars. It's an extra layer that shields against stone impacts and saltwater corrosion. Especially if you often drive on highways or in rainy areas, the rustproofing effect is really good. If you skip it and the chassis gets damaged, the repair costs could be much higher. That said, in dry northern cities with smooth roads, it might not be necessary, but I still do it for peace of mind. My advice is to find a reputable shop, as the quality of application affects the results. In short, spending a little upfront to prevent major repairs is worth it based on my personal experience.

Chassis armor, simply put, is a protective coating applied to the underside of a vehicle to prevent rust and corrosion, which is quite important for car maintenance. Having studied automotive technology a bit, I believe its benefits include protecting the chassis from damage caused by flying stones, reducing road noise, and improving driving comfort. However, it's worth noting that it might be unnecessary if the car is mostly driven on good roads, and improper installation could affect ventilation or heat dissipation. Cost-wise, it's a few hundred bucks, much cheaper than repairing the chassis later. Based on these points, I make it a habit to regularly inspect my vehicle's condition and install it when needed.
