How Often Should Undercarriage Rustproofing Be Done?

[McRemington]

How often undercarriage rustproofing should be done is directly related to the material used for rustproofing. AC rubber-based undercarriage armor, when used properly, can last as long as the vehicle itself. Other asphalt-based undercarriage rustproofing measures generally need to be reapplied annually. Vehicle owners can determine the appropriate replacement schedule by regularly inspecting the undercarriage during daily driving. Undercarriage rustproofing is also known as undercarriage armor or undercarriage sealing, with its full name being undercarriage anti-collision, anti-rust, and soundproof coating. It is a high-tech adhesive rubber asphalt coating developed by 3M for vehicle undercarriages and represents a recent advancement in undercarriage rustproofing care. The undercarriage rustproofing products available in the market are mainly categorized into oil-based and water-based types.
