50-100 Bitumen Underbody Coating

50-100 is a durable bitumen-based underbody coating with a thixotropic, quick-drying formula that forms a strongly adhesive, elastic film. It reduces chassis noise and shields cars, trucks and buses from wear, rust and weathering. Easy to spray and formulated for long-term corrosion protection on vehicle chassis.
