Carbon paste also has an isolating aspect, as in galvanic action is reduced. I don't know about carbon to carbon but I have seen carbon to both Ti and Al galvanic corrosion causing frozen seat posts.


I should add that there have been many carbon frames and posts which have had grease applied to them with no damage other then the clamping torque concerns. Calfee once said that there was no substance available from your local hardware store that would damage well cured carbon. Andy.
