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. Properly applied with the 3M™ Cavity Wax Plus Wand Kit, it remains pliable and will not chip, peel or crack.
3M™ Cavity Wax Plus protects against corrosion in concealed locations Developed specifically as a corrosion protectant on interior automotive panels and structural components, our 3M™ Cavity Wax Plus is typically applied to areas including door skins, vehicle sills, interior quarter panels and frame rails. It is formulated for use on bare or primed automotive metals including steel or aluminum, and can be simply sprayed on in coats to protect critical interior joints, hem flanges and repair welds where moisture can form over time. The non-hardening interior corrosion protection material remains soft and pliable and will not crack, chip or peel after application. Spray-on material in an easy-to-use can eliminates the need for bulk spray technology, allowing instead for easy application after painting and welding.
