Cavity wax is used to prevent the formation of rust in cavities or grooves. Sometimes, these areas are not easily accessible and can develop rust formation easily. The best cavity waxes available in the market are easy to use, solvent-free, Eco-friendly, and generally non-toxic. They are also known as short film waxes. Most cavity waxes can be removed easily using detergents and water. Sometimes, white spirit and other solvents can also be used to remove the waxes. Depending on the type of application, cavity wax must be chosen properly.
The first kind of cavity wax is used for vehicles. This is generally used for body work. They are available in aerosol bottles and can be easily sprayed. They are used to protect the inside of the chassis, hollow spaces, and other framework in automobiles. For the protection of the outer surface of the car, special epoxy wax is also used. This is also a type of wax, but it adds extra shine to the car, making it look better. Cavity wax is generally transparent, but for some, pigmented cavity wax is also available. This wax comes in different colors. It can be used to highlight the presence of the wax or for some other reasons. It is used in industries.
There is also a special type of cavity wax which can be used only for painted surfaces. This wax is thin and forms a transparent layer over the painted surface. Thus, the painted surface is protected from rust, and it also looks better. All types of cavity waxes can be left just like that until they wear off or they can also be removed. When a new coat of wax is applied, it is generally advised that the old coat be removed.
