How important is Mold Release and Conditioner for Resin and Molds?
I cant find any at joann's craft store or michaels. I dont have a hobby lobby near by, and I'm just trying to save money as far as shipping and whats necessary and whats not.
Is this release/conditioner really important for using EasyCast Resin?

depends on the kind of mold you're using. Silicone - less important. Plastic - more important.
Joanns' should have the cast'n craft mold release. There are also places you can buy it online for not much.

Well if it's RTV silicone and resin I only use a mold release when making the mold, not when casting. The cheapest mold release is Dawn dish soap! Works like a charm.
The best thing to do is every once an awhile depending on the age of the RTV mold, baby powder it to help break the surface tension so you don't get pin holes in the resin casting.

I've never found resin stuff at JoAnns but Micheals does have it. The stores I've been to have it on a bottom shelf in with all the glues. Hobby Lobby also carries it.
Here is an Etsy seller who offers it:

I've always used the mold release with all my molds. Both the ones made for resin and the silicone ice cube trays. It's been difficult to remove some pieces occasionally even when using it so I think it would have been almost impossible without it.

Silicone molds should not require a release agent. They should be wiped out with mild, soapy water after each use. Plastic molds usually need a release of some kind. I have found that a fine mist of Pam cooking spray works well. In fact, I think Pam now has a "silicone" based spray.
