Acetone as a skin cleaner is not a good idea.  Although acetone itself is
not know to be absorbed appreciably through the skin, it does damage the
skin.  Damaged skin is more prone to allow absorption.  Also a solution of
partially reacted epoxy resin and hardener is more likely to be absorbed
than a thick gel of the same materials.  Vinegar works, but it smells.
Waterless handcleaner also works and is not as hard on the skin as a
straight solvent.  Cheap disposable gloves are a very good idea, avoiding
skin exposure is better than trying to wash the goo off.  

As someone noted in this thread epoxy is not fully cured for several days,
long past the time it appears to be hard to the touch there are unreacted
components present.  When you sand epoxy you should wear a particulate and
organic vapor respirator.

Epoxy resins and the hardeners are sensitizers.  Once you are sensitized you
may never be able to work with or around the sensitizer again.

Personally when I work with epoxies I wear nitrile gloves, a respirator with
super cartridges (organic vapor, amine, acid gas, HEPA, + combo).  If I am
working where I will be generating lots of dust, sanding the bottom of a
boat vs. sanding a spot repair on a paddle, I will also wear disposable
coveralls.

I also suggest you read the vendors Material Safety Data Sheets and safety
recommendations on their webpages.  When you cut through the sales
hyperbole, I think you will find the above is a reasonable summary of their
recommendations.  It also fits with the information I have found from
sources other than the vendors.

As for the source of my "authority" I do safety and health for a living and,
work with epoxy to fix stuff at home, so I looked the data up for myself.  I
suppose I need a disclaimer here so, remember boys and girls, my free advice
is worth what you paid for it.
