Nash Knotloc Glue has an on-going list of uses, ranging from gluing leaders and rigs to mending anything you manage to break on the bank side.
I always apply a few blobs of knotloc glue to my rigs and leaders just for that extra added security aspect. The fast setting and easy to apply applicator has a use for everything. It provides me with confidence that all my knots are 100% secure and there is no chance of a lost fish due to a knot pulling. Nash Knotloc glue is one of those things I really would struggle without and it has served me extremely well over the years. With the small amount of space it takes up, slip one in your tackle box; you never know when you might need it!
