Propyl alcohol is particularly good for unset epoxy resins. It
is, I
think, sold by chemists as surgical spirit. I have not tried it
on
natural resins yet.


Surgical spirit is mainly ethanol, not propanol. The really good
safe stuff
for getting resins, (including, i should imagine, conifer resin),
off hands
is Loctite 7855 hand cleaner, but I don't know whether it's
available in
retail outlets.

We are both wrong. I have just had a look at the Penguin Dictionary
of Chemistry. According to that, sugical spirit it methyl alcohol,
further denatured by the addition of castor oil, diethyl phthalate and
methyl salicylate
