Superglue is fine usually, but it has a limit when it comes to durability.
This thing called JB Weld, holds 300kg/cm2 and is waterproof and heatproof.
After 24 hours it is cutable, sandable and paintable. Doesnt shrink or break when drying.
Doesnt smell, isnt poisonous.
Might be useful for boards, bars etc too.
Only downside: needs 24 hours to dry - pretty bearable Id say.
One set will travel with me from now on for sure
