What is Automotive Chassis Armor?
2 Answers
Automotive chassis armor is a high-tech adhesive rubber asphalt coating that protects the vehicle's chassis during operation, preventing damage from sand and stones, and also avoiding rusting of the chassis during use. Automotive chassis armor features non-toxicity, high coverage, and strong adhesion. The functions of automotive chassis armor include: 1. Impact resistance: During driving, flying gravel can hit the chassis, causing significant damage over time; 2. Undercarriage protection: Protrusions on different road surfaces can wear down the chassis; 3. Corrosion prevention: In regions with frequent rainy seasons, such as southern areas, acid rain can easily splash onto the chassis, leading to corrosion; 4. Heat insulation: In summer, high ground temperatures can cause heat to transfer from the chassis into the vehicle.
I've seen many car owners applying undercoating to their new vehicles. Essentially, it's a thick, elastic protective coating sprayed onto the steel plates underneath the car. Veteran drivers always told me that cars in coastal areas are most prone to underbody corrosion—high salt content in the air combined with rainwater can cause the undercarriage to rust like a honeycomb within just a few years. This undercoating forms a rubberized layer that blocks moisture and also cushions against stone impacts. Last month, I watched a technician perform the application: they first thoroughly clean off any grease from the underbody, then use a high-pressure spray gun for even coating. Professional shops apply at least four layers, and when dried, it’s like wearing rain boots—both moisture-proof and wear-resistant. DIY applications with purchased materials tend to be less effective, as it’s hard to reach corners without a lift, and insufficient thickness reduces sound insulation. Recommended for vehicles frequently driven on rough roads, while city drivers might skip this expense.
