Interior Insulation

I used Dynamat on my last build and will be going in a new direction this time.

On the mustang I pretty much created a solid shell from the firewall back. Entire floorpan, firewall, trunk, doors.. everything. The car was more solid, but sound was not decreased as much as I expected.

This time I'll be trying out Second Skin.

Instead of a complete layer I'll be using strips of Damplifier Pro. With that method a basic door pack or maybe a trunk pack should be plenty of material.

Once that is complete I'll be covering it with their Luxury Liner Pro.

This combination should cut resonance down substantially with the Damplifier and reduce overall in cabin noise with the Luxury Liner. It'll probably be an easier install than the full shell treatment as well.
