Common brands of chassis armor materials include Henkel, 3M, and Chief. Introduction to Chassis Armor: The scientific name of chassis armor is 'Automotive Underbody Anti-Collision, Anti-Rust, and Soundproofing,' which is a high-tech adhesive rubber asphalt coating. It features non-toxicity, high coverage rate, and strong adhesion, and can be sprayed on exposed parts of the vehicle such as the chassis, wheel hubs, fuel tank, underbody panels, and trunk. Types of Chassis Armor: Asphalt-based Underbody Rustproofing Coating. This is the earliest type of chassis armor product, with the only advantage being its low cost. However, asphalt tends to develop numerous cracks after drying, and water trapped in these cracks can cause a 'battery effect,' leading to more severe rusting of the vehicle's chassis. Oil-based (Solvent-based) Underbody Rustproofing Coating. This type of product contains many toxic substances harmful to human health, so its use not only endangers human health but also damages the ecological environment. It has been banned in many environmentally stringent countries in Europe and America. Water-based Underbody Rustproofing Coating. Since its diluent is water and it contains no toxic substances, it is also known as an eco-friendly underbody rustproofing coating. Composite Polymer Resin Paint. As a fourth-generation chassis armor material, it boasts high waterproofing, elasticity, corrosion resistance, and noise reduction properties.
I'm an average car owner who mainly drives in urban and suburban areas. To protect the chassis from rusting, I've researched many brands. 3M's undercoating is very famous, and I've used it myself—it offers strong waterproofing, so I don't worry when driving on wet roads after application. Rust-Oleum is also good, more affordable, and available at chain stores, making it suitable for first-time DIYers. Another option is Loctite, which a friend recommended as professional-grade with excellent durability, though it requires some skill to apply. If you're on a budget, Fluid Film is an option—it's a bit greasy but decent for rust prevention and easy to spray on. Before installation, make sure to thoroughly clean the chassis; otherwise, dust can cause the coating to peel. I think this investment is worth it—a one-time application can last years, saving repair costs and hassle.
