Spray activator for cyanolitic glues

With this activator spray, all cyanolitic glues will dry within seconds.
This is a particularly interesting method of filling gaps. The correct procedure is to apply first the provided spray to the surface, let it dry and then apply the glue. If you apply the glue first and then then use the spray, the resulting reaction can cause the glue to turn white. For example, it is often used in bowmaking to fill in worn areas such as where the thumb rests on the grip.
