I think my brother must have left it here on one of our wilderness backpack trips.   I used it last time on my braid to flouro FG knot and it stayed tight!  
 

probably very much overkill, but it seems to button down the tiny cut ends. 
 

Anyone using this stuff?  I think it would be a good lube to cinch tight instead of saliva and then hit it with the UV light to cure. It cures soft and pliable. 

no pic so I have no idea what glue you are talking about but I use UV for all my fly tying.  the flex stuff from solarez is awesome stuff and I use it on foam poppers and also to make a welded loop on fly lines that the loop is busted.  You don't need a light either, just being in the sun for a little but will dry it pretty quickly.  

This is the stuff I used. 
 

 

Gotcha.  I am not a fan of loon UV products for tying but I haven't used this stuff.  

I don't even wet my knots anymore. Just pull the tight gently and slowly. Hasn't been any issues.
