undercoating

Vehicle belly sealant

Undercoating is a protective layer applied to the underside of a vehicle to prevent rust and corrosion from road salt, moisture, and debris.

The term also refers to the material itself, typically a rubberized or waxy compound sprayed onto metal surfaces.

More generally, undercoating can mean any base layer applied beneath a finish coat, as in painting or manufacturing.

The mechanic recommended undercoating for the new truck before winter.
