As a new buyer I was underwhelmed by this product`s performance. As a result of my tests, I determined that the adhesive does not hold up well in water-based environments, despite its "water-resistant" claims. The only pro I can offer is that the packaging is easy to use .However, the con of this product far outweighs any convenience - it simply does not deliver on its promises. My advice? Look elsewhere for a truly industrial and scientific adhesive..
