3M Cavity Wax Plus Internal Corrosion Protection Coating 511g 3 Pack

3M Cavity Wax Plus is a professional internal corrosion protection coating developed to protect concealed automotive body cavities and structural components from moisture and corrosion. The non-hardening, self-healing formula penetrates seams, lap joints and enclosed sections to provide long-lasting protection following collision repairs and panel replacement.

Designed for use on bare or primed steel and aluminium, Cavity Wax Plus is ideal for protecting door skins, rocker panels, frame rails, quarter panels, pillars and other enclosed body cavities where factory corrosion protection may have been compromised during repairs. It remains soft and flexible after application, allowing it to continue flowing into seams and crevices for ongoing protection without cracking, chipping or peeling.

The convenient aerosol can provides fast, even application and can be used with the optional 3M Cavity Wax Plus Applicator Wand Kit to achieve complete 360° coverage inside difficult-to-reach body cavities.

Trusted by professional collision repair centres worldwide, 3M Cavity Wax Plus helps restore corrosion protection to repaired vehicles while supporting OEM-recommended repair procedures.

Great product let down by poor packaging

Cannot fault the product, works really well. Easy to apply, although 3 cans was barely enough to do my car. The only let down was the applicator wand kit I'd ordered, by the time it got to me, was in a million pieces. Needed to be better packaged to prevent the brittle tubes from breaking in transit. Otherwise great product, would buy again without hesitation.
