        Too hard to extrude.
        We only bought this about three months ago and finally tried using it, it was pretty much dried out and impossible to get it out, we soaked it overnight in a tub of water and we were able to get some more out, but it stopped being usable again. Since it's been more than 90 days we probably won't be able to get a replacement, but I wouldn't have expected it to dry out so fast.

            Used it to seal a crack in my radiator plastic reservoir for the antifreeze. Didn’t want to use the regular silicone I had because only rated to 170 degrees

            It went on like any other caulking. It dried even in less than 40 degree temps. I won’t know how the fire block part works unless the house burns down.

            Very good adhesion and the consistency makes it easy to dispense. It works well for filling gaps with minimal shrinkage.
