Felt lockers installed in a number of cars do not allow for external noise insulation of wheel arches using the recommended technology. This problem is solved by a special version of NoiseLIQUIDATOR mastic.
The mastic is applied to a wheel arch liner that has been previously cleaned of dust and moistened with water. This allows for the installation of a STP Noiseblock 2 soundproofing membrane on the treated wheel arch liner and even greater protection for the driver and passengers from the annoying noise of the road surface. In combination with the classic NoiseLIQUIDATOR mastic for wheel arch metal, the new STP development allows for even greater sound insulation on cars with felt lockers.
