Aquaseal is great stuff for sealing leaks in waders. However, there have been questions on how to prevent it from hardening in the tube after it's been opened. I found that squeezing from the bottom of the tube and not mashing it in the middle helps a lot. When I am finished with an application, I make sure all of the air is out of the tube by rolling up the bottom of it. I then refrigerate it.
Today I used some from a tube that I stored about a year ago. Other than a small solidified plug under the cap, it was relatively fresh. I don't know if refrigerating it is necessary, but I'm sure that getting the air out is.
