I have an old army jacket which I think is Gore-Tex (its says MVP material on a label.) In the long past it was my favourite jacket but... the seams are all taped inside and some of this tape has begun to fall away. The tape is still intact and I'm hoping I can just stick it back on. But what with? I wouldn't want to damage the jacket, nor fix it poorly. I'm guessing it ought to be done similar to sealing tent seams?
