Chassis armor can be classified as follows: Asphalt-based chassis rustproofing adhesive: Asphalt-based chassis rustproofing adhesive is the earliest rustproofing product. Its only advantage is being inexpensive. However, after drying, asphalt tends to develop cracks, and water trapped in these cracks can cause a " effect," accelerating rusting of the chassis and causing greater harm to the vehicle. Therefore, it is best to avoid using asphalt-based chassis rustproofing adhesive for chassis armor. Oil-based (solvent-based) chassis rustproofing adhesive: These products contain toxic substances harmful to human health and can damage the environment. As a result, they are rarely used in environmentally strict regions like Europe and America. Additionally, the adhesive layer of oil-based (solvent-based) products is very hard and prone to cracking when slightly bent, lacking elasticity and providing poor noise insulation for the chassis. Water-based chassis rustproofing adhesive: Since its diluent is water and it contains no toxic substances, water-based chassis rustproofing adhesive is also known as eco-friendly chassis rustproofing adhesive. Currently, this type of product is widely preferred in Europe and America. Water-based chassis rustproofing adhesive offers strong adhesion, good elasticity of the adhesive layer, and excellent noise insulation for the chassis, making it the preferred material for chassis armor.

When it comes to the classification of chassis armor, I believe there are mainly two types: coating type and protective plate type. The coating is an anti-rust liquid layer sprayed onto the chassis, similar to paint, providing rust and corrosion protection. It's suitable for urban car owners, especially in areas with heavy rainfall. It's easy to apply but requires regular . As for the protective plates, they are solid metal or plastic panels, such as engine underguards or transmission guards, installed directly on key areas to prevent scratches and impacts from stones. These are more suitable for off-road vehicles frequently driven on rough terrain. The choice depends on your driving environment: coating is sufficient for urban daily use, while thick protective plates are better for the wild. I've seen many car enthusiasts use a combination of both for comprehensive protection. Chassis safety is crucial—don't let minor issues turn into major repairs.

When it comes to the classification of chassis armor, coating and protective plates are the most mainstream options. Coating, simply put, involves spraying rust inhibitors or coating materials, forming a thin layer on the metal surface. It's easy to apply and can even be a DIY project, saving both money and effort. Protective plates, on the other hand, are more complex, divided into plastic and metal plates. Plastic plates are lightweight and rust-resistant, while metal plates are heavy-duty and impact-resistant, effectively blocking road debris. I recommend beginners start with coatings—pick a sunny day and try spraying it yourself. For protective plates, it's better to hire a professional to avoid installation errors. Don’t forget the material categories: PVC coatings are cheaper but wear out easily, while alloy plates are more expensive but durable. Proper chassis protection extends your car’s lifespan, and you won’t have to worry about rust during long trips.

Chassis armor is divided into two categories: coatings and guards. Coatings are rust-proof sprays, while guards are cover plates such as engine guards. Coatings are suitable for corrosion protection, whereas guards protect against physical damage. In terms of material, coatings can be resin-based, while guards are made of plastic or metal. Installation is simple for coatings (DIY), but guards require professional tools. Regular inspections can extend their lifespan.

From an economic perspective, chassis armor can be categorized into coating type and protective plates. The coating type is cheaper and cost-effective, costing only a few dozen yuan to apply, but it offers limited effectiveness, mainly preventing rust. Protective plates are more expensive and come in plastic and steel variants. Plastic plates cost a few hundred yuan, providing scratch resistance and being lightweight, while steel plates cost over a thousand yuan, offering collision protection and sturdiness, making them suitable for off-road vehicles. The choice depends on budget and needs. For city driving, the coating is sufficient, while off-road enthusiasts may prefer steel plates. After weighing the costs, less makes it more worthwhile, so avoid unnecessary expenses and complications.

Chassis armor is divided into coatings and underbody panels. Coatings are sprayed with anti-rust layers to prevent corrosion, suitable for simple daily use; underbody panels come in plastic and metal versions, such as lightweight plastic for scratch resistance and heavier metal for impact protection to safeguard the engine. I focus on the importance of underbody panels during off-roading, which must withstand high and low temperatures and resist impacts, with significant material differences. When driving on mountain roads, protecting the chassis is the top priority, and regular cleaning extends the protective performance.
