Our 3M™ Undercoating protects vulnerable automotive metal parts from corrosion and abrasion. Specifically designed for automotive undercarriages, wheel wells and body panels — quarter panels, under hoods, trunks, undersides of floor pans — it's equally effective in many other automotive applications. Multi-purpose aerosol undercoating is available in a rubberized formula that can be painted.

Protect the Metal
Available in two forms, our 3M™ Undercoating is a cost-effective solution to protect vehicles from road damage and corrosion. Both feature an aerosol formula that offers excellent sprayability and good coverage to bare or primed metal.

3M™ Undercoating, PN 08881, is a black, multi-purpose, aerosol undercoating with a matte finish and a medium to coarse texture. 3M™ Underseal™ Undercoating, PN 08882, is a rubberized formula. Also with a black, medium texture finish, this coating can be painted.

Integrity of the Seal
Any automotive procedure that disturbs the seal of an undercoating, such as panel replacement or collision damage repair operations, may leave the metal unprotected and result in corrosion. Proper recoating of these surfaces with service-type anti-corrosion material is essential. Our 3M™ Undercoating is an excellent choice for protecting areas most vulnerable to corrosion and impact from the road, where paint alone isn't enough.
