First of all, this is not my first joint adhesive. I tried to unload your product, but unfortunately nothing happened. With 2 hands and all my strength, I couldn't squeeze out more than 1/4 teaspoon. Yes I opened it at the spout and I have a good quality gun. I was on a roof in 90 degree heat and your 17.47 product didn't come out. I had to throw it away and use another product, extremely dissatisfied. I suppose it must be old. I'm just letting you know
