Stage 2) Add a barrier layer over the top of the deadening. This secondary treatment targets exterior airborne noise that is not directly generated by the body panels. It is a Barrier treatment to block unwanted noise intrusion into the cabin from outside. 100% coverage is recommended for the affected areas.

Treat the boot and cabin floor to help block road ,exhaust noise and tyre roar.
