Why should the cavities in vehicles be treated with a cavity sealant?

The cavities in vehicles, such as doors, fenders, and engine compartments, are often difficult to access and difficult to clean areas. Therefore, moisture and dirt can easily accumulate in these areas, which can lead to rust and corrosion. A cavity sealant is a treatment applied to these areas to protect them from moisture and dirt.

Cavity sealants are usually made of a wax or oil base and often contain additional additives that contain rust and corrosion inhibitors, UV stabilizers, and other protective materials. When this treatment is applied to the cavities, it forms a barrier that keeps moisture and dirt out, thereby preventing rust and corrosion from forming.

A cavity sealant is particularly useful for older vehicles that already show signs of rust and corrosion, as well as for vehicles that are operating in humid or saline environments. It is also a good idea to apply a cavity sealant to new vehicles to ensure their protection from the start. However, it is important to note that a cavity sealant is not suitable for all vehicle types and models and it is better to follow the manufacturer's recommendations.
