To finish off a clean and well-protected Exhaust Insulating Wrap application it's recommended the use of 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 11 oz. coating comes in black and aluminum colors.
The high heat coating is only flammable when it is coming directly out of the can. Once it dries on a product it is no longer flammable.
This is considered hazardous good for air shipment, air delivery is available but can be very expensive.
