Anyone know of any sponge material that is resistant to toluene?  I have a
spray application where the spray heads, to avoid gumming up, are immersed
in toluene.  This leads to a fairly large evaporation.  My thought was that
a sponge material would keep the heads wet with toluene, but would minimize
evaporative loss.  I am open to suggestions.
