Was wondering where in the rules it would prohinbit you from applying a sound deadener to the back side of a metal dash? The vehicle is an older Chevy with a factory metal dash.

3-10a Modifications to the passenger compartment from the B-Pillar forward are prohibited.
Additional Guidelines:
· The OEM headliner (or an equivalent replacement) must remain in place for those areas in front of the B-Pillar.
· The OEM door panels (or an equivalent replacement) must remain in place for those areas in front of the B-Pillar.
· The OEM carpeting (or an equivalent replacement) must remain in place for those areas in front of the B-Pillar.
· Sound damping materials may be used to reduce vibration when installed in accordance with the manufacturer’s recommended installation instructions. For those areas located in front of the B-Pillars, the maximum total thickness of sound damping material applied at a given point may not exceed 5/32 inch (4mm). The sound damping application may consist of mat-type material, spray-on material, or a combination of the two. A maximum of 2 layers of mat-type material may be used in any application, even if the total thickness of the sound damping material(s) is less than 5/32 inch (4mm). For those areas located behind the B-Pillars, an unlimited amount of sound damping material(s) may be used.
· Expanding foam may be used sparingly in front of the B-Pillars to seal small openings or reduce vibration, but may not be used to fill voids or other large cavities (such as the dashboard or doors). An unlimited amount of expanding foam may be used behind the B-Pillars.
Maybe this is the question you also need to ask, Does the manufacturer’s recommended installation instructions include the dash?
