Aqua Proof Paste is the magic goop for installing bottom brackets and keeping them quiet. In the Kogel office it's known as 'Shut up Grease'. Aqua Proof is developed by Morgan Blue from Belgium for the off shore industry. It's salt water resistant, does not degrade over time and a long time favorite of the UCI world tour mechanics. It works on any pressed or threaded surface to avoid corrosion. You'll find yourself using it for a lot more than just installing bottom brackets. The 5ml size is for a single bottom bracket installation, the 200ml jar will last a long time, even for professional use.
