As far as anti seize goes….it works. Not much else to say except that if you are a home (bike) fettler, there is enough in the tube to keep you going for a long, long time.

Can certainly say this stuff really reminds me of copper slip if not the exact same just without the copper slip name and colour but it does the job and maybe prevents future stem creaking, will have to wait and see on that one. but overall good stuff.

Used this for the pedals tread and bike fork. Works as meant to be, not had issues over past 3 months of use.

I applied this to my bike pedal, and all noise has gone. It works.

Pedals slip on and off with ease. This stuff is the business. Used on cleat bolts also.
