I am not sure but I believe the Rain-X was used just on the surface of one of the pieces of glass to allow the emulsion not to stick to that piece of glass. I believe if you treaded both peices of glass the emulsion may lift off the piece of glass it was meant to stick to.

Rain-X will not stick to gelatin at all. I believe it is silicone. It is important to only coat one side.
