COLLA21 CyanoAcrylate glue 21gr DENSE
This is the glue we use commonly in all our projects, and we feel safe to tell you it is the best. Just be sure to leave it open a minute after use, without cap, to allow the glue that is still in the tip to flow back to the bottom. This way, it will never block. This DENSE version, is closer to a gel, while normal one acts  like water.
It can be used in combination with the stunning activator spray, that leaves no residues but allows the glue to get rock solid in literally seconds. This way, this glue can be used also as a filler/putty.
