    Use wood finishing wax (minwax) as the mold release. Let it set for a few minutes before pouring in the foam.

    X2, wax is the way to go.

    Are there 'undercuts' that are hanging up the removal? Also agree that 'waxing' is the way to go.

    Cory Keep an eye on quality!

    It does sound like you have "keys" that are keeping the mold from coming apart freely.

    u need to wax and let the wax dry and then buff it to a shine several times is better
