Some may find it very useful when building durable flies, for example or gluing two components which may flex or are subject to temperature change.
The Loctite 4851 is not as flexible as polyurethane Aquaseal, but still has decent flexibility, and is the only flexible Loctite.
# 4861 has the same properties and higher viscosity.
The glue is recommended for applications in -65 F to + 125 F ( -53 to 52 C) range.
