Slippy seat post (but not the usual kind of slippy)

Go to it . . . use it . . . it is your friend.

It is designed for Carbon parts (which has a low friction coefficient) - but works just as well on metals/plastics.

Not only does it stop stuff from slipping, but when you come to taking stuff off/apart it magically acts like grease and helps stuff come apart easily.

I know that sounds contradictory - but it works like this, it is made from millions of tiny rubbery spheres - when under pressure, when the part is clamped down, these spheres squash and deform to form a dense paste with a very high friction coefficient - but when you loosen up the part for removal the spheres return to their original spherical shape and help to 'roll' the surfaces away from each other.

You only need to use a very thin layer, so a tub like the one above should last many years.

I know all about it.. you gave me the same sales pitch ages ago (I may have wiped your memory of the meeting) which is why I finally bought some. I think I may have the tub but my memory is failing me..
