3M 4014 SOUND AND VIBRATION DAMPING PANELS
from Aircraft Spruce & Specialty Co in Atlanta, Ga.
Great stuff for this purpose. I installed it in corp aircraft for 40 years.
I removed the heat shield material from the doghouse, installed sound damp and re-installed the heat shield. Love the outcome.
I do plan to cover the floor and other areas soon but will use the fatmat for that.
This photo is full sound damp foam before heat shield reinstalled.
