CAVITY WAX PLUS 18.7OZ CAN - 3M Automotive

The 3M Automotive CAVITY WAX PLUS 8852 is a professional-grade internal corrosion protection coating, delivered in an 18.7 oz aerosol can, specifically engineered for modern collision repair and long-term rust prevention. This formulation provides controlled, even coverage inside hidden cavities where OEM e-coat may be thin, damaged, or missing, enabling technicians to restore pre-repair protection levels and reduce future corrosion issues.

Key Features

• Non-Hardening, Self-Healing Film: Formulated to remain soft and pliable, this film actively reflows with heat and vibration to seal minor cracks and seams, ensuring consistent, long-term corrosion protection without chipping, peeling, or cracking.
• Active Rust Prevention Chemistry: This coating effectively protects bare and primed steel and aluminum in enclosed areas, guarding against moisture, salt, and other road contaminants.
• Aerosol Convenience: The 18.7 oz aerosol can provides a fine, controllable spray pattern, eliminating the need for bulky spray equipment and making it ideal for collision centers and fleet maintenance.
• Excellent Flow and Wicking: Engineered to penetrate tight overlaps, hem flanges, spot-welded seams, and boxed sections, this wax ensures uniform internal coverage in challenging areas.
• Wand Kit Compatible: Designed for seamless integration with the 3M™ Cavity Wax Plus Applicator Wand Kit (sold separately), enabling 360° coverage inside rocker panels, frame rails, pillars, and other deep cavities.

Applications

Use 3M 8852 Cavity Wax Plus on internal automotive body structures, including 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 many OEMs recommend the application of internal anti-corrosion material during body repair.
