Review on Copper Anti-Seize Stick by Loctite - 20-Gram Size by Ian Iknokinok

I use this on my folding bike seat post. The saddle rises and falls twice with every ride, all sorts of debris creeps in and turns the bike into a noisy coffee grinder. A few dabs of copper paste on the part of the post that slides into the seat tube will help avoid this annoyance and ensure a smooth installation and removal every time.
