what release agent for platinum silicone molds?

i don't normally use platinum silicone so unsure of what to use. i'm just using up a little i had.

i know this stuff is a bit awkward sometimes.

i have a piece that requires a 2 part mold. a bottom and a top.

the bottom is already poured, i need to stop the top pour from sticking to the lower.

what do i use?

i use spray wax and or vaseline on tin silicone no problem.

i did search google but f. all info.

please only reply if you actually know, not looking for guesses.

thanks
