This adhesive has held my projects together well but is too flexible for some uses. I only gave it 4 stars because it is another contact adhesive that needs to be applied to both surfaces and allowed to dry for 3 minutes before mating for a strong bond. In many cases, unless the pieces are broken into 2 pieces, they will not separate easily at all, especially within 3 minutes. On the plus side, the glue is quite viscous, which gives it time to bond. before assembling the parts. And the best thing is that there is a metal pin in the middle of the cap that inserts into the metal dispensing tip when you close it after use. This is the best lid I have ever seen with an all purpose adhesive. This feature should allow you to use the glue many times without drying out or clogging.
