Is Car Chassis Armor Necessary?
2 Answers
Car chassis armor is necessary as it quickly dries to form a firm elastic protective layer that prevents impacts from flying stones and gravel, and protects the vehicle's chassis metal from moisture, acid rain, and salt corrosion, thereby preventing rust and ensuring driving safety. Steps for applying chassis armor: 1. Raise the car and rinse the chassis with a high-pressure water gun, then apply an engine exterior cleaner or degreaser to remove adhered oil and sand, or use special sandpaper to remove the original rust-proof layer; 2. Use an air gun to blow out water from gaps and dry with a towel; 3. Prepare to spray the rust-proof treatment layer by covering the tires and exhaust pipe surroundings with masking paper and tape, ensuring sensors and shock absorbers on the car body are well covered; 4. Spray each component of the chassis armor onto the chassis in sequence to a thickness of 4mm; 5. Perform local repairs with surrounding areas masked; 6. Clean non-sprayed areas with a special cleaner and allow to air dry.
I personally think underbody coating is absolutely necessary, especially if you drive frequently in northern regions like I do. In winter, road salt has strong corrosive properties, and over time it can cause the underbody to rust and perforate, leading to expensive and troublesome repairs. After installing underbody coating on my car, even after several years of driving, the underbody still looks as good as new. It not only prevents rust but also cushions against stone impacts, protecting the wiring and components underneath. Although the installation costs some money, it’s far more convenient than regular wax maintenance. Whether driving in wind or rain, the anti-corrosion effect is obvious, significantly extending the vehicle’s lifespan. In short, for car owners in harsh environments, it’s definitely a worthwhile investment—spending a little to save a lot of trouble.
