Key Features

• Non-Hardening, Self-Healing Film: Formulated to remain flexible and actively reflow, this film seals minor cracks and seams to provide consistent, durable corrosion protection without chipping or cracking.

• Aerosol Convenience: The 18.7 oz aerosol can offers a fine, controllable spray pattern, streamlining application without requiring specialized spray equipment.
• Excellent Flow and Wicking: Engineered to penetrate tight overlaps, hem flanges, spot-welded seams, and boxed sections, ensuring uniform internal coverage in challenging areas.
• Wand Kit Compatible: Designed for seamless integration with the 3M™ Cavity Wax Plus Applicator Wand Kit (sold separately), allowing for 360° coverage inside rocker panels, frame rails, and pillars.

Applications

Use 3M 8852 Cavity Wax Plus on internal automotive body structures such as door skins, rocker panels, quarter panels, hatch and trunk cavities, and pillars. It is particularly valuable after panel replacement or structural repairs where OEM coatings have been compromised around welds and seams. This product is suitable for passenger cars, SUVs, light trucks, and commercial fleet vehicles, helping to restore factory-like internal corrosion protection as recommended by many OEMs during body repair.
