| If there is a mold involved, then this is a problem with all major processes - hand layup, vacuum bagging or infusion. With vacuum bagging and infusion the non-mold surface is covered with peel ply, then the bag, but the mold side is laid out directly on the mold with its release compound.

Sure. But I think II uses plastic as the mold release generally, as rob has said many times, because its cheap, and PP on that, then fiber. So I guess II is different.
