The important thing is a little heat and the mix. dont'be stingy on the powder. If you are you can get a gummy mess that won't cure. I had that issue with a glue job. I was able to take a putty knife and heat gun and get my backing off the bow.
All my bows are glued with Urac and all are completely wrapped up.
Note. Sodium chloride is the active setting agent. The brown powder is just walnut flower. If you get raw sodium chloride you can get a "Clear Urac". 13:1 is the mix ratio of the Sodium Chloride. Basicaly a drop in enough glue with make a trilam.
