I've never tried this, and it's obviously too late for the
victim who started this thread, but here is one suggestion for
dealing with a recent poison oak contact:

Rinse (not just wipe) with (ordinary cooking) oil.  The idea is to 
carry AWAY any residue
of the Urushiol (or Crushiol, the offending oils produced by poison
ivy/oak) in a solvent that it is more soluble in and that won't act
as a carrier facilitating absorption.  The Merck Index lists alcohol
as a good solvent for urushiol, and this may work too, but it's possible
that this could act as a carrier facilitating absorption; even here,
however, rinsing with plenty of alcohol, followed immediately by rinsing
this off with alcohol MAY work as well.

I suggest this based on having accidentally gotten the oil of a chili
pepper in my eye.  Water, either cold or warm, was useless.  The offending 
molecule here, capsaicin, has a few structural features in common with
urushiol, in particular a benzene ring with two oxygen and one alkyl 
substituents.  In that instance, rinsing with (olive) oil quickly got the
out and provided immediate relief.
