I'm not sure what "LF" is supposed to stand for, but the tape for the mount is a 3M VHB tape (VHB = Very High Bond). You can get it in rolls at most hardware stores or amazon and then put two strips on, cut to size. The one I got off amazon.ca was "Scotch Extreme Mounting Tape". Most people prefer to get black tape as it tends to be less noticeable than the normal grey tape.What is it called so I can search for some?
