Loctite Super Glue
Loctite Super Glue is a powerful solvent with a plethora of uses, some quite practical in the bike shop. The venerable stick-anything-to-anything glue, now over 70 years old, is now available in a mechanic-friendly gel, allowing for precision application without dripping or running. A single drop works well to constrain loose binder bolts; apply a slender line to the two edges of a cut tire for a solid patch, strong enough to withstand full pressure.
A useful addition for shops and on-the-road kits.
