Well that was a quick test... I used 40 weight clear silicone oil put it in a tiny clear spoon then put a few drops of resin on top.

First thing I noticed, the resin was more dense so it sank to the bottom of the spoon.

Then I took it outside for curing and it cured within seconds.

So that's not the wonder material.

Tried it on some PDMS too, no appreciably difference in regular PDMS and silicone impregnated. They both seamed to release with ease.

So we need to find something cheap, clear, more dense than resin and oxygen permeable.
