Grease also makes the seatpost stiffer and as a result, it starts cracking up. Carbon paste just fills the gap to increase friction. It also makes it easier for you to adjust the seat post and gives you a smooth experience.

Carbon paste doesn’t smell bad and doesn’t ruin the paint that much. So carbon paste is safe all the way.
