True, but once you add the catalyst your time is cut down to a matter of hours. Freezing it slows down the hardening. I froze about 1/3 of a gallon and used it about 4 months later. It was definitely thicker but still usable. It's still in my freezer - it's been over a year now. Not sure what kind of state it's in....
It does work really well. My motorhome was badly neglected as far as roof sealing goes. I brushed the stuff on every protrusion and all the leaks were gone. One leak did re-appear, but because I hadn't secured the roof rail down properly. It worked loose and cause another breach. It's great stuff and will find and seal all but the biggest of holes.
