I seem to recall back in the second ice age, in one of the first consultant design offices I worked in right out of school, where we spent as much time in the shop building things as on the board designing them, that when we needed multiples of a critical part, we made an RTV mold and cast the parts in resin. Then there was this small "vibration table" that one of the guys had built that we put "fresh pours" on to bring any bubbles to the "surface," which was, of course, the unseen bottom of the part! 
A generous application of "tincture of green soap" (procured from the local apothecary,) once dry was an excellent mold release ... just remember to wash the part thoroughly prior to applying any paint!
