What is Chassis Armor?
2 Answers
Chassis armor, technically known as chassis anti-collision, anti-rust, and soundproof coating, is a high-tech adhesive rubber asphalt coating developed by 3M for vehicle chassis. It is non-toxic, has high coverage and adhesion, and can be sprayed on exposed parts of the vehicle such as the chassis, wheel hubs, fuel tank, lower body panels, and trunk. After rapid drying, it forms a strong elastic protective layer. The following are the functions of chassis armor: 1. Prevent safety accidents caused by chassis scraping. 2. Protect against impacts from flying stones and gravel. 3. Avoid moisture, acid rain, and salt erosion on the metal parts of the vehicle chassis, preventing rust and corrosion, and ensuring driving safety. 4. Reduce noise by lowering body noise and blocking road noise during driving, improving comfort.
Chassis armor is applying a thick protective coating to the underside of the car, mainly for rust and scratch prevention. During my last maintenance, the mechanic recommended installing it since I often drive on rough suburban roads. After application, it really helps - you can hear a muffled sound when gravel hits the chassis, unlike the previous sharp pinging noise. The coating has a texture similar to asphalt mixed with rubber, offering great elasticity when dried, making it particularly suitable for winter road salt and coastal humid climates. The best time to install it is right after getting a new car, when the factory chassis is still clean.
