One trick that Dow recommends for its Sylgard 184 is a mold release agent. I
think in reality it's a cure inhibitor. It's a 1 or 2% (by volume) solution
of Liquinox. You dip your substrate in that solution and let it air dry.
Then apply the PDMS.

In theory this should work for a wide variety of substrates.
