i bought this rtv silicone sealant stuff at walmart and squeezed it all into a small plastic box. Then i put a worm in it. I did exactly what you do for plaster or liquied rtv. I did all of that and the mold is just about to be 24 hours cured and 11 oclok tonight. Iv'e noticed it is real soft and its still not cured in the middle of the mold. Since its a sealant i think it blocked off air to let the rest cure. Will it eventually after a couple days cure? Or should i do something to it like drill a couple smalls holes in the bottom. If i need to do something what should I do? THANKS!!
