I am in a bit of a pinch and looking for a quick solution to buying something that will act as a mold release from my local store (Walmart). Any advice would be appreciated.

(1 part unscented dish soap to 2 parts 99% isopropyl alcohol works well) with a clean brush over all mold surfaces. Allow release to dry for at least 30 minutes.
For casting resin in a silicone mold, I always use baby powder. I tried an actual mold release from a supply company and went back to the baby powder after just a handful of casts with the spray release.
Dry lubricant with Teflon (or Cerflon, same thing). I've been using Liquid Wrench brand with great results, I get it from Ace Hardware.
In my experience metal powders act VERY similarly to talcing a mold. I've cast some parts with intricate details without any noticeable bubbles appearing, all by coating the mold with my metal powder.I have a questions about using Babypowder. I use i so that the resin flows into all the smaller details and eliminate air bubbles. But if i also want the part to be coldcasted How would i powder the mold?.. Or does the metal powder work the same as the baby powder so i don't need to use it?...

Like Nick said, when you cold cast, the metal powder will basically take the place of the baby powder. So you only need the metal powder in those cases. I skip any kind of mold release when using metal powders for cold casting.
Just be super cautious with metal powder and use an appropriate respirator. They are not fooling around with the warnings on that stuff. I dropped a teeny bit of aluminum powder on the carpet in my office and now have a half dollar-sized spot of aluminum infused carpet. Nothing has gotten the powder out. Now just imagine that stuff in your nose and/or lungs!

I've seen you mention this before, how would you compare it to ease release 2000?
