How to install soundproofing to back wheel arches
Preparation to installation
Clean and degrease the surface.
FIRST LAYER – VIBRO-DEADENING
Use Bomb Aero 4,2mm as a first layer instead of Aero 2,3mm. Since it is bitumen mastic, you have to use a heat gun to install it.
SECOND LAYER – SOUND ABSORPTION
Apply the noise-absorbing material STP Biplast 10 mm as the second layer. STP Biplast is also heat-insulating material.
