Products like 3M 5200 and 4200 keep fine until opened. Once opened, the entire tube seems to cure in just a day or two, wasting the remainder of the tube.
I seem to recall someone posting that this curing could be slowed down by refrigerating or freezing the opened tube. If you've tried this, did it work? Any other suggestions for prolonging the shelf life of an opened tube of sealant?
