[QUOTE="ducatipaso, post: 8243910, member: 644396"] Well today I set everything up to test the roofing cement & took lots of pictures. When I opened the can of roofing cement it was black & shinny and the texture looked dense. It looked to have maybe three different sizes of matter, a bonding paste and two or maybe three larger textures. I dipped a steel ladle in to scoop out some cement and it came out with easy but then it didn't want to come out of the ladle. Last week I purchased a 1100 watt hot plate and today I a purchased a small sauce pan with a lid from the thrift store. So I scooped the roofing cement into the sauce pan and heated it. On the label it said - do not heat container not - do not heat continents of container / roofing cement, so I put the cement in a sauce pan. The cement didn't have much odor and I heated it to 150 degrees, it softened up some but it didn't melt into a pourable liquid at that temp. I laid out 10 sample pieces of roof shingle, cereal box card board, thin foam matte, metal & plastic screen. Then I spread around the gooey black cement and watched its texture as I worked with it and bonded tougher different combinations of samples. Then I set them aside to cure, after they cure I will test the adhesion, tensional strength & its flexibility it feels. At the last minute I decided to use a piece of screen as a test piece and the cement worked very well with plastic screen. I put a gob of the cement on a piece of cardboard and then laid the screen on top and used another piece of card board to spread the screen into the cement. The screen conformed to the shape of the cement and a percentage of the cement pushed thru the screen. I was pleased by that. I made a bit of a mess when trying to work the cement into the cavity of my C70's upper motor mount but it was another chances for me to work with the texture of the cement. I wasn't wearing rubber gloves and without thinking I dipped my finger in to get another gob of cement, then it occurred to me that it might be hard to clean the cement of my hands. But when I purchased the roofing cement I also purchased some low grade paint thinner and the paint thinner dissolved the cement very quickly. On the front of the label it said for vertical applications and on the back it said something about possible a 30 day cure time. The long cure time means it might not work for my C70's motor mount, becasue if I try to accelerate the cure time by using tomuch heat the oils might evaporate to quickly and cause the cement to become brittle, brake and then powder when the mount is in service. The roofing cement is messy but when combined with roofing shingles & thin insulating foam pad it will work for many areas of my C70 sound damping project.
