[sdiy] Reproducing plastic fader shafts / knobs at home? ~``~

[Harry Bissell Jr]

I'd expect you'd need a mold release agent. In making plaster of
  paris casts, Vaseline (petroleum jelly) is often used. But is that
  compatible with the Shapelock ??? Who Knows

would come right out once it hardened or might there need to be something 
(what?) between the mold and the plastic for it to come out easily?
Thanks!
