Just a tip from an "old timer" on extending the life of CA type glues. When finished using the glue wipe excess from tip with paper towel,

gently tap a bottom corner on a hard surface to get glue back to the bottle and then put the nozzle back on as tightly as possible. the

nozzle will not clog, the glue stays in liquid form, and the nozzle is not "impossible to remove.

The oldtimer who taught this and many other "tricks" to me is gone now but some of his glue is still usable after many years.
