getting down to the metal ( floor )

[weq92f]

Getting ready to do some sound/heat proofing, heat mostly! Right away I've found that the carpet is glued to the carpet pad. The carpet pad is glued down to what appears to be about a 1/4" thick rubber which is glued down to the metal. There may or may not be some sort of coating on the metal as well, not sure yet.

Looks like this rubber mat like bottom layer goes up to about as high as the bottom of the A/C unit. I'm going to cut off a piece of it to get a closer look.

It is starting to look like a PO painted some kind of sealant directly to the cab floor then glued down this "rubber" like thing and so on. If I decide to rip all this stuff out and redo it with known materials, what kind of cleanup of the cab metal is necessary to place down these vibration dampening DynaMat type materials?

If it requires clean metal then I may just rethink the whole thing!
