If this is the same stuff that is used pre skimming then I am still
using from a gallon container which must be at least 10 years old by
now, I use it watered down for sticking labels to envelopes and sticking
down flaps on cardboard boxes. It is still `strong` as everytime I have
to make a new mix I have to use pliers to open the container. :-)
