Hi Martin,

    Thanks for the response.. Think my "falling down" might be your No
    3. question.

    Bill's book says use the paint brush method with the brush connected
    to the cathode.. However does that mean that I should connect the
    anode to the titanium strip which is in the bath. Usually it is the
    other way round.. I.e. cathode to bath and anode touches the object
    in the bath to cause the colouring. I couldn't see any bubbles
    forming around the brush or in the bath..Your help is much
    appreciated.
