How to install soundproofing on the hood
Preparation to installation
Clean and unoil the surface.
FIRST LAYER – VIBRO-DEADENING
Use STP Aero 2,3 mm as a first layer. It’s a vibration-damping mastic material. To install the first layer, you have to measure the size. You can use a ruler or a tape line. All the parts of the material must be rolled down.
SECOND LAYER – SOUND ABSORPTION
The second layer is STP AeroFlex 6 mm. It’s waterproof foam rubber with an adhesive base. This sound-absorbing material also serves as a heat-insulator.
