I have been using latex surgical gloves when working the bees.  The
gloves greatly reduce the amount of propolis I somehow manage to cover
myself with and the stings that I do receive are not as nasty because of
the latex.  If the amount of alarm pheromone gets too high
(characterized by repeated attacks to the same area), I remove the
offending glove and use another one.  One note of caution, some people
may have an allergic reaction to latex.  Another potential problem is
that in hot weather your hands tend to sweat a lot.  The sweat will
accumulate in the gloves which generally results in "prune hands" and  a
quantity of water in the fingertips if the gloves are not on tight.
