I have a mountain hardware softshell jacket that has a zipper that is separating. It isn't a sewn section, but was either glued or maybe melted together?
Any suggestions on how to fix this? I suppose I could sew it back together, but wondering what else might work.
Seam Grip has worked well for me through multiple washes for things like adhering patches to down jackets, but in this case you have something under tension. On top of that, an adhesive may not adhere well to whatever heat tape was used previously. Sewing would be the most foolproof.
