after removing everything to install my damp pro i noticed there seemed to be some material on the floor of my car i think it is sound deadener.
so my question is do i remove it to put damp pro on the metal or lay my damp pro over the factory deadener?
im hoping jon will chime in, i spoke to him to see how much and what i should get for my lancer
i have 80sq ft of damp pro 5 sheets of llp 1 sheet of heatwave pro and 2 sheets of overkill
