When you first open I had the problem that the discharge tube stuck in the cap and could only be removed with pliers. I then plugged in once by hand in Tube. Since then, she holds. There is a point deduction.
If the adhesive should dry up in the cannula, the cannula can be done again consistently by being heated briefly with a lighter.
As has been written, the adhesive is (almost) exclusively for model building, not for other Kunstoffarbeiten!
