3M 04274 NVH dampening material is the right stuff.
Like other 3M products, it is expensive but great quality.
Requires a special gun for twin tube cartridges that is not cheap. You can make do with a cheaper more common twin tube gun designed for larger cartridges if you use some cardboard as a spacer to hold the smaller tubes in the gun.
