Sounds llke a plan. I washed surfaces with soap, water, and sponge. The self-adhesive on the Stinger adhered well. I then sprayed the Stinger with Permatex hood liner and stuck the Dynamat sound insulation to that for two layers of sound and heat attenuation. In two years it never separated. There was already a thin layer of foil backed insulation on the bottom of the floor boards but not very effective. Besides sound, there was a noticable difference in the floor temps around the engine cowling.
