[QUOTE="ducatipaso, post: 8247370, member: 644396"] Today I laid a layer of thin foam down on the floor pan under where the passenger seat goes, the rear foot well area and where the rear seat mounts. Then I used the roofing cemented to bond some roofing shingles "that I had already cut" for the areas to the foam. I sealed the edges of the shingles to the foam with kind of a thick layer of cement that over lapped onto the top of the shingles. I was spreading the roofing cement with a wooden kitchen spatula. I had a used a double thick pieces of cardboard as kind of a mixing board and would ladle a scoop full of roofing cement on to it and then use the spatula to transfer the cement to the shingles. then I would work the cement back and forth using the spatula like a spreader to create a even coat of cement. Then I would bond the shingles to the foam. when I laid out the foam I had to cut it to fit and used some masking tape to seal up any seams. I later realized that duct tape would bonded to the shinny foam better and I really needed to be using 2inch wide tape instead of inch wide tape. But anyway after I had the shingles bonded & sealed to the foam I added another layer of foam and sealed it into place with roofing cement. I used about half of the gallon of roofing cement on the areas mentioned. My original plan was to sound dampen the doors during this phase of the build so it looks like I either need to go get some more roofing cement, or put the doors back tougher and then sound dampen them when I build some speaker baffles.
