Interesting video.
I watched a video on microtechnology and nanotechnology (don't know how to
find it again somewhere in youtube) that explained where a coating like
that came from.  It was developed by NASA so dust wouldn't stick to the
instrumentation and parts of the martian rover.  It had proved a problem
with all the things they took to the moon.  It works opposite the way you
think that it would work.  The surface only looks smooth at the visible
scale.  When you look at it microscopically it is a constantly dividing
nanosurface that resists sticking because it is so UNsmooth that particles
can't find a place to settle.  It is all tiny bristly points,  but they are
so arranged that particles also don't tend to get trapped between them.

Why worry about wax on your boots and gloves (the carpet is another
matter)?  I mix 25% wax with mineral oil and use it to waterproof and
soften boots and gloves.
