I gave a friend a profile design FFWD alloy seatpost in order to use his carbon roadbike for a triathlon.
The seatpost was a very tight fit, I could not use carbon paste because it would no longer fit.

Is there any risk by doing so?
-Galvanic corrosion
- a too stiff alloy post in a more flexible carbon seat tube

if ridden in the wet, a metal loaded antiseize like park tool asc-1 might be best. and redo grease/antiseize every now and then, more often if there are wet rides
