Does a New Car Need Undercoating?
2 Answers
According to the owner's needs, choose whether to apply undercoating. If you frequently drive on special road conditions, it is recommended to install it. Below is a related introduction to the advantages of automotive undercoating: Corrosion Protection for the Chassis: The car chassis is exposed during daily use and is prone to rust. When driving in relatively humid environments, residual wash water on the chassis can, over time, corrode the car chassis, leading to rust. Applying undercoating can help protect the car's chassis from corrosion. Reducing Impact from Stones: During driving, small stones may be kicked up. At high speeds, the destructive force of these stones increases, potentially causing damage to the car's chassis. After applying undercoating, the destructive force of small stones can be mitigated, protecting the car's chassis from being punctured by stones, which also contributes to the maintenance of the car's chassis.
When I first got my new car, I also hesitated about whether to apply undercoating. New cars come with some protective coating on the chassis, but if you often drive on bumpy roads or in rainy/snowy conditions, applying an extra layer is definitely worth it. It prevents rust, protects against stone chips, and reduces corrosion damage to the chassis. Since my car mainly drives in the city with clean roads, I skipped it and saved some money. However, for long-distance driving or coastal trips, undercoating adds an extra layer of protection. I suggest evaluating your driving environment first—if you frequently drive on highways or in humid climates, investing a few hundred bucks isn’t a loss. For smooth roads, regular car washes and maintenance are enough to keep things hassle-free. Periodically check the chassis condition and touch up minor scratches promptly to save on long-term repair costs. Overall, whether you need it depends on your driving habits and location—just make a flexible decision.
