How to Determine if There's Damage When the Chassis Hits a Flat Surface

[JohnFitz]

When the vehicle's chassis is hit by an unknown object and you cannot determine if there is any damage, it is recommended to drive the car to a 4S shop or repair shop for inspection. Most repair shops will have chassis lifts, and once the vehicle is raised, any scratches or damage on the chassis surface can be easily identified. Methods to prevent chassis scratches and damage include: 1. Applying chassis armor: Automotive chassis armor can be sprayed on exposed parts of the vehicle such as the chassis, wheel hubs, fuel tank, lower panels, and luggage compartment. After quick drying, it forms a strong elastic protective layer that not only prevents impacts from flying stones and gravel but also avoids corrosion from moisture, acid rain, and salt on the metal parts of the chassis, preventing rust and ensuring driving safety. 2. Installing an engine guard: Engine guards are designed specifically for various vehicle models to protect the engine. Their primary purpose is to prevent mud from covering the engine and to protect the engine from damage caused by impacts from uneven road surfaces during driving.
