Tommmmmmmmmmmmmmmmmmmmmm Sumo/Regal advised me to use copper slip on my seat post when I was suffering the same issues
Tacx carbon paste would be better, despite the name it works just as well to prevent slipping on metal to metal interfaces.
On the other hand, an aluminium post is a steel frame shouldn't slip unless you're a real porker, as long as you tighten it properly, which is where the torque wrench comes in. 8Nm is about right.
