Is Chassis Armor Necessary for New Cars?

[DiKyle]

It is advisable to install chassis armor on new cars to prevent rusting. The specific reasons are as follows: 1. Cheaper cars may rust due to inferior materials. Due to price and brand positioning constraints, these vehicles often cannot use high-quality sheet metal materials, making rusting a hardware issue. Generally, more expensive cars use costlier materials like hot-dip galvanized steel, all-aluminum materials, high-strength composites, and automotive carbon fiber, which are naturally resistant to rust. For instance, all-aluminum bodies and chassis rarely rust. 2. External environmental factors can cause chassis rust. This mainly depends on the usage environment. Some areas have poor conditions with frequent exposure to acid rain or corrosive dust; others have humid climates or heavy rainfall, leading to severe chassis corrosion. Additionally, rough road conditions can cause frequent chassis impacts or gravel strikes, damaging the surface and increasing the likelihood of rust-prone areas, such as the engine underguard and exhaust pipe. 3. Human factors contribute to chassis rust. Driving frequently through waterlogged areas keeps the chassis in prolonged contact with water, causing rust. Infrequent car washing, especially after rain, allows rainwater to corrode the car body. Parking in high-humidity areas like beaches or riverbanks can also accelerate rust. Neglecting exterior maintenance, such as washing or waxing, and failing to clear accumulated water in the exhaust pipe tail further exacerbate the issue.
