3M™ Cavity Wax Plus is a non-hardening corrosion protective coating for bare or primed aluminum and steel automotive inner body panels and welded structural components. The material is designed to cover and seal interior joints, hem flanges and compromised e-coats where corrosion can form. When properly applied with the 3M™ Cavity Wax Plus Wand Kit, it remains pliable and will not chip, peel or crack.
Developed specifically for corrosion protection on internal automotive panels and structural components, the 3M™ Cavity Wax Plus 08852 is formulated to coat and seal areas such as door skins, rocker panels, interior quarter panels and frame rails. It is excellent for use wherever OEM e-coat may be compromised during the repair process, as well as on new replacement parts.
