I got some as a trial; it does not work for my application.   

I have managed to get a pinhole free surface......on the female side a the part (the "B" side)  On the male side, its still full of gaps.  Its very bizare.  I have used the wax paper and the plastic carrier as releases, both work, but the wax leaves the surface pinhole free.  unfortunately I cant use the wax paper on the mould.
