Pros

  • +Effective for tent seam retreatment
  • +Can be precisely applied with a syringe for detailed work

Cons

  • -May require a significant quantity for extensive repairs
I'd put that seam grip in a plastic syringe with a small tip and inject it on the seam. Then with a small model brush brush it in the seams or threads.
