Innerpanel cavity wax is a type of wax that is specifically formulated for use in the inner cavities of automotive panels. It is a chemically formul
ated wax-based rustproofing that creeps and penetrates into cracks and close-fitting areas. It creates a barrier between the metal and the environment, acting as a rust inhibitor, helping protect the metal from rust and corrosion. Innerpanel cavity wax typically comes in clear/amber and black colors.
Innerpanel cavity wax is typically applied using a brush or a spray gun. It also comes in a DIYer kit (see link below) that does not require any special equipment for application. The wax is applied in a thin and uniform layer, making sure to cover all the areas that need protection. Once applied, the wax should be allowed to dry completely before any additional coating or painting is applied. Typical coverage when spraying is approximately 100-150 sq ft per gallon at 4-6 mil wet coat.
The wax is usually applied after the panel is cleaned, when coming from the manufacturer, but it can be applied into a hard-to-reach area, without prior cleaning, when working with a used vehicle. The wax can be applied to bare metal and painted over, or it can be applied over top of paint. Innerpanel cavity wax is typically applied as a liquid, although some manufacturers also offer a spray-on version. Taping off electrical wires and connections is unnecessary when spraying innerpanel wax as it does not affect electrical systems or door and window mechanisms.
It’s important to note that the use of Innerpanel cavity wax is not a permanent solution and will need to be reapplied periodically to maintain its effectiveness. It’s also important to make sure that the wax is compatible with the paint or other coatings that will be applied on top of it.
