> 3 dayUsed to keep moisture from between parts which pr vents rust, and keeps parts from literally seizing together. This isnt grease.

> 3 dayWorks really well. Ordered this to lube all the threads putting together a new bicycle. The seat wouldn’t stop squeaking while I was riding, so I took it apart and lubed the assembly. No more squeak. Oh, and it’s also pretty important if you want to be able to maintain your bicycle beyond the initial assembly:)

07-06-2025Works as it should. I use this on pedal spindles, stem bolts, etc and have not had problems using a standard hand torque hex getting my bolts to release. I am a heavy and strong rider so my I put a lot of pressure on my threads; so far this product has protected my threads as advertised.
