Review on Expending Foaming Upgrade Caulking Suitable by Danny Zapata

It was a disaster. I have followed the instructions. I had the valve closed trying to screw in a can of Great Stuff Pro. It immediately started foaming before it was fully screwed on, but since the valve was closed, the foam could only drain to the sides. The pressure of the foam caused the glass to get stuck halfway. I couldn't keep turning it or taking it off without two sets of locks, but there was so much foam and so fast that I couldn't even find anything to hold on to. When I unscrewed it the whole jar was empty and there was foam everywhere as you can see in the picture.
