    Not sure what kind of "kit" you are using.  But I know there's been
    a recent flurry amongst enamelists about the "Imagon Ultra"
    photopolymer film that is supposed to be an excellent resist for
    copper in order to achieve detailed clean lines for etching.  It's
    the reverse of PnP blue in that it is for intaglio etching -- where
    the black lines are what get etched.  There is an enormous amount of
    info about this at www.polymetaal.nl    (they go into great detail
    about techniques, etc.)  go to their page on intaglio etching --
    resists and transfers.  They give you the complete "how to" guide. 
    I also know this is available from Daniel Smith art supplies.  You
    can also purchase just the resist from Thompson Enamel 
    www.thompsonenamel.com   look under "what's new"    As far as
    mordants go, I don't know of much else for copper other than ferric
    chloride, but I think Dick Blick Art supplies sells something call
    "copper etching solution"  Might want to check with them about that.
    www.dickblick.com   If anybody has results to report about their
    experience with the Imagon Ultra resist -- I would love to hear
    about it since I have yet to try it -- but heard it works pretty
    well. Kelly   indigoflameworks AT hotmail.com
