My hood has the shakes at low RPMs and some highway speeds. I took the hood insulation off and noticed most of the black goo bonds between the structural and sheet metal of the hood has separated.

Since I recently painted my car, I don't want to experiment.... So what kind of product us that stuff? Silicone? Urethane? something cool i don't even know about?
