Does Undercoating Have Any Effect?

[McBrielle]

Here are the functions of undercoating: 1. Anti-corrosion for the chassis: Northern regions have rain and snow weather, while southern regions have rainy and foggy weather. Moisture naturally corrodes the car's chassis over time, and residual wastewater after car washing can also cause certain damage. However, undercoating forms a protective film on the bottom of the car. 2. Protection against stone impacts: While driving, vehicles often kick up small stones, and the impact force of these stones on the car's underbody is proportional to the vehicle's speed. 3. Thermal insulation: When the air conditioning is turned on, the cold air inside the car sinks, while the hot air outside rises, eventually gathering near the car's chassis for exchange. Therefore, the protective effect of the car's chassis directly determines the vehicle's cooling efficiency. 4. Prevention of underbody scraping: Each layer of undercoating can be 1.2-2.5 mm thick, reducing damage when the car's bottom is scraped by protruding objects. 5. Savings on maintenance costs and car value preservation: The chassis supports the car's four major systems, so protecting the chassis means protecting these systems, saving a series of maintenance costs. Typically, rust starts to appear on new cars after about three years of use. Correspondingly, the better a vehicle is maintained, the higher its value. After some time of driving, whether for personal use or preparing to trade in for a new car, a vehicle that has undergone undercoating protection (especially with quality assurance from reputable large companies) will undoubtedly have higher value.
