Installation Instructions
Installation Instructions
- Remove plastic panels, upholstery, and insulation to expose bare sheet metal.
- Remove debris, rust, and waxy oils. Clean surface with denatured alcohol (NOT a degreaser).
- Cut sound deadening material using a utility knife - either freehand or using a template. We recommend wearing gloves.
- Remove wax paper backing. Stick tacky butyl adhesive to metal surface.
- Use a Wooden Hand Roller to roll out any air pockets and create a permanent bond. A better bond further increases performance.
- Combine with a second layer like Luxury Liner Pro for the ultimate way to soundproof a car.
