The exposed surface of your silencer, under the car, brushes against bad roads, stones and is splashed with muddy water causing the silencer to rust and leak. UE Silencer Coating Treatment provides a protective coating for silencers of all types of vehicles from corrosion and rust. The silencer washed and degreased before the ue Protective Coat is applied with Body Schutz gold gun. The UE Body Schutz/Undershield provides a hard coating on the underbody of the car that is fast-drying, paintable, rubberized, non-toxic and chip-resistant. The coating minimizes sound from underneath the vehicle and insulates against the heat and cold. UE Silencer Coating Treatment increases the life of the silencer. The silencer also acquires diesel wash resistance and performs better at high temperatures.
