I ordered the 3M 06384 Automotive Acrylic Plus Tape which seems to be what everyone on the forum recommends. The last time I ran a bead of the lock-tite down the center of the tape around the ends, attached it to the glass, and set a bag of potting soil on it for two days to give it some weight to encourage it to stick. Still no luck.
I saw someone the other day driving by that had one on a silver IS and I almost hunted them down to ask how they got their's to stick.
