Two things go wrong with seatpost insertions. One is that they keep slipping. The second is that due to corrosion the seatpost freezes solid and won't come out. Carbon paste sounds good for preventing slippage. But does it offer any protection against corrosion if used to stop a metal post slipping in a metal tube? If not, it is no use. It will just swap one problem for another that is even worse.
An aluminium seat post will corrode quite nicely inside a CF frame for the same reason as it will inside a steel frame. I haven't experienced that using Motorex CF paste (link)
