Make sure the clamp bolt is not bottoming out at the coincidental torque to give you SOME clamping force but not ENOUGH.
I've read that grease on carbon posts does something bad like penetrate the epoxy, making the post slip even more and after that, difficult to remove the grease's effect.
Measure your 31.6 post to verify it's not undersized.
According to my Sutherland's manual, the seat tube for your particular mating of steel frame to aluminum post, the seat TUBE can be as large as 31.8mm and still work with your post. Ideally, the seat TUBE would be no larger than 31.65mm.
You could have the "perfect storm" of an oversized seat tube AND undersized seat post.
My only concern with using carbon past is, will it prevent rust in the seat tube and impair seizing of the seat post.
