I am a huge fan of my E600 glue, and not so much of Teflon zippers. My all time favorite robe’s zipper split earlier this week. The pull was half way up with the bottom portion standing wide open. What to do? I wrangled it around until I managed to yank the right side of the pull out of the left side. Once I had everything back in a position of normalcy, I did notice there was no way the union of the two were meshed as before for a smooth ride up. I glued the beginning of the bottom of the zipper with a good thick gob of glue. I then left it dry for a day before I dared to try it out. Above the bottom inch of the glued zipper in the robe, the zipper does go up and down. I now have a step in robe.
