3M 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 3M protective coat is applied with Body Schutz gold gun. The 3M 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.

3M Silencer Coating Treatment increases the life of the silencer. The silencer also acquires diesel wash resistance and performs better at high temperatures.
