Is it necessary to armor a car?

It is necessary to armor a car. Chassis armor is a rust-proof care project for the car chassis, which is a rubber-like coating sprayed on the car chassis. After spraying, it quickly solidifies to form a strong and elastic protective layer. The functions of chassis armor include: 1. Effectively protecting the chassis from the impact of road gravel and preventing minor scraping and friction; 2. Preventing corrosion of the chassis iron plate by acids, alkalis, and salts; 3. Preventing loosening of chassis screws; 4. Reducing noise transmission during driving and increasing driving tranquility; 5. Blocking heat conduction from the chassis iron plate, keeping the cabin warm in winter and cool in summer; 6. Protecting the driving safety of the car owner.
I've loved driving since I was young. Underbody coating isn't mandatory, but if you live near the coast or in rainy, humid areas, it can significantly extend your car's lifespan. Without coating, rainwater and salt can corrode the metal components of the chassis, potentially causing rust holes in just a few years and compromising the vehicle's structural integrity. After applying the coating, I noticed much less noise from road debris hitting the underside, making highway driving quieter and more comfortable. The downside is the considerable cost – a full application can run several thousand yuan, which might not be cost-effective if you plan to change cars in a few years. I recommend applying it when the car is new, using eco-friendly coating materials that both protect the vehicle and slightly improve its resale value. For those frequently driving on mountain roads or gravel-heavy routes, underbody coating is essential. Ultimately, the decision should be based on your driving environment and budget.
I've been driving for decades and am budget-conscious. Undercoating isn't necessary unless you frequently drive on construction sites or in saline-alkali areas. In regular city driving, as long as your car's chassis is in good condition, regular washing and waxing are sufficient. Undercoating is costly and troublesome, requiring frequent checks for coating wear—it's not worth it. You're better off saving that money for better tires or upgrading your AC. I've seen friends who got undercoating only to have their cars rust after flood exposure—total waste of money. Focusing on good driving habits to avoid chassis impacts is far more important.
I have some knowledge about car maintenance, and underbody armor is worth considering. It acts like a protective coat, preventing corrosion and rust, especially when applied during the new car stage. Modern materials like polyurethane coatings are lightweight and effective, capable of shielding against mud and water impacts. If not done, the underbody is prone to damage during humid seasons. The cost is manageable, and it can save repair expenses in the long run. I recommend simply consulting a mechanic.
