Do Sedans Need Underbody Armor?
2 Answers
Sedans do not require underbody armor. The functions and timing for underbody armor are as follows: Functions of Underbody Armor: Underbody armor is a high-tech adhesive rubber asphalt coating that protects the car's chassis during operation, preventing damage from sand and stones, and avoiding rust formation on the chassis during use. It features non-toxicity, high coverage rate, and strong adhesion. Timing for Installing Underbody Armor: Generally, after about 3 years of vehicle use, if inspection reveals severe scratches on the chassis from bottoming out and the factory-applied armor has been damaged, it is necessary to address it promptly.
I've been driving sedans for almost ten years, living in a northern area where roads are heavily salted in winter. My first car, without any undercoating, had its chassis rust through after a few years, and the repair costs were outrageously expensive. For my second new car, I applied a protective coating, and now after seven or eight years, the undercarriage is still as clean as new, with much less noise too. Although new cars come with factory rustproofing, an extra layer of protection helps guard against rain erosion and stone impacts, especially when driving on mountain roads or during rain and snow, giving more peace of mind. I think it's particularly worthwhile for owners who frequently drive on rough roads or in humid areas—costing just over a thousand yuan, it saves a lot more money and hassle compared to repairs, and extends the car's lifespan. If you're in a dry environment, you might skip it, but prevention is always better than regret.
