Seatpost slipping

I have a new Planet X SL Red with the stock planet X seatpost.

No matter what I do it keeps slipping after about 4 or 5 miles, not by much maybe 1-2mm every 4 miles.

I have tried removing the post, degreasing and cleaning the post and post mount and the seat tube, I have tried using hair spray but nothing works. I have tightened to the correct torque setting and even gone beyond but still it keeps slipping.

I was thinking of using some wet and dry to make the post more 'grippy' but I don't want to invalidate my warranty.

Thoughts?

    Carbon assembly paste?

    Causes carbon surfaces to bind at lower torque levels. Slightly granular paste.
