    Too many years ago to remember I made RTV molds of flat items. I had
    a liquid that when painted on a cured layer of RTV a second layer of
    fresh RTV would no stick to the original layer. Is there still such a
    liquid and if so what is it and where can I buy it. 

    The process I used was: I laid down a layer of modeling clay and
    build a wood frame (before I knew there were aluminum frames) around
    it. I poked depressions in the clay to act as locking lugs. I laid
    the flat wax model with sprue on top of the clay so that it stuck to
    the clay. Poured RTV on top of the clay and wax model. When the RTV
    cured I turned the whole thing over, coated the cured layer of RTV
    with the liquid and poured another fresh layer of RTV on the
    original. The cured RTV mold could be separated at the painted joint. 

    I don't get around much any more and my knowledge of RTV mold making
    is somewhat limited. I am probably describing a process many of you
    use. Its sort of like telling everyone how to make a wheel. 

Sure could use some help
