To finish off a clean and well-protected Exhaust Insulating Wrap application it is recommended to use the Hi-Heat Coating. 

The coating will protect the wrap from abrasion and harmful liquid spills. Extra resins and binders toughen the surface, extend the life of wrap by protecting it from friction, and seal the pores to minimize the penetration of harmful liquids. 

The coating also works excellent as a paint directy on metal surfaces.
