    If the coating is only a few atoms thick (as with a flashed vapour
    deposit) wouldn't it be safer to use a Q-tip type applicator dipped
    in aqua-regae(sp?)? 

    This way the acid wouldn't get some where it shouldn't, but there
    should be more than enough to remove the small amount of metal
    required. 

    Hydrofluoric acid is about as nasty as acid gets, you should invest
    in gloves (gauntlets?) that are rated for this acid as the effects of
    it on the human body ain't nice..... 

Cheers, Thomas.
