No, regular grease reduces friction, which is the opposite of what a carbon clamping joint needs, and can actually cause a seatpost or stem to slip even when properly torqued. Carbon paste works the other way, adding grip so components stay put at safer torque values, so it should be used at any carbon-to-carbon or carbon-to-metal clamping interface instead of grease.

Clean both mating surfaces thoroughly first, then apply a thin, even coat of the paste to the areas that will be clamped together, such as the inside of a seat clamp or stem faceplate. Tighten the bolts to the manufacturer's specified torque, ideally using a torque wrench, since the paste's grip means you do not need to overtighten to prevent slipping.

While it is designed primarily for carbon fibre interfaces, it also works well on carbon-to-metal joints, such as a carbon seatpost in an aluminium frame, or an aluminium stem clamping a carbon handlebar. It is generally not necessary on purely metal-to-metal joints, where standard torque specs without paste are usually sufficient.

Carbon components are often designed to be tightened only to a light torque spec to avoid damage, and without extra grip at the clamp surface, that lower torque alone may not be enough to prevent slipping under riding loads. Adding a thin coat of carbon paste at the interface usually resolves persistent slipping without needing to exceed the recommended torque.

Since only a thin coat is needed at each clamping joint, a 20 gram tube covers a good number of applications across seatposts, stems and handlebars. Keep the tube sealed when not in use to keep the paste at its intended consistency for future use.
