[Closed] KS seatposts and mud

Im not having much fun with my KS dropzone(like an i900), new in November- came on the bike

but its sticking/slowing after wet and/or muddy rides- which is every ride its ever had to be fair

any tips on keeping them running sweet

or should I just dig the gravity dropper out of the shed, send it back to the importers for servicing and sell it on?

ks recomend slick honey, anyone know of any other lightweight greases I can use
