3M™ Cavity Sealant Wax Plus is a non-curing corrosion inhibitor for interior body panels and welded structural components made of bare or primed aluminum and steel. The material can be used to cover and seal interior joints, flanged edges, and damaged electrocoating where corrosion may form. When applied correctly with the 3M™ Cavity Sealing Wax Plus Applicator Kit, it remains pliable, does not crack, and has good peel and stress crack resistance.

3M™ Cavity Sealing Wax Plus protects against corrosion in hidden areas. 3M™ Cavity Sealing Wax Plus is specifically designed as corrosion protection for interior body panels and structural components. It is applied, for example, to door skins, door sills, inner side panels, and frame beams. It is specifically designed for use on bare or primed automotive metals such as steel or aluminum. The wax can be easily sprayed on in layers to protect critical interior joints, flanged edges, and damaged electrocoating finishes where moisture can accumulate over time. The non-curing material for cavity corrosion protection remains soft and pliable. Once applied, it does not crack and offers good peel and stress crack resistance. The spray-on material in a convenient can eliminates the need for messy industrial spraying techniques, allowing for easy application after painting and welding. Use 3M™ Underbody Sealant Wax Plus with the 3M™ Underbody Sealant Wax Plus Applicator Kit PN8851WK to reach hard-to-reach areas.

The 61-cm and 86-cm tubes enable a 360-degree, comprehensive spray pattern for perfect coverage. With the applicator set, exactly the right amount of protective spray can be applied to inner sills, zigzag parts, interior structures, frame rails, and other concealed areas with tight tolerances.
