Do modern cars still need undercoating?
1 Answers
It depends on the specific situation. Here are the reasons: 1. Many new cars already come with factory-applied underbody protection, making additional undercoating unnecessary. However, if the purchased new vehicle lacks such protection, applying undercoating becomes highly advisable. 2. Undercoating doesn't involve installing a physical protective device on the car's chassis. Instead, it refers to spraying a 2-4mm thick layer of elastic sealing material underneath the vehicle. 3. The primary purposes of undercoating are to prevent rust formation on the chassis and reduce the impact of road debris during driving. Additionally, it provides thermal insulation and noise reduction benefits.
