Release Agents

[Jimbo890]

I wanting to test a mold pattern with some of the Smooth-On VytaFlex 60 Urethane mold rubber. I've never used this stuff before, but I know I'm suppose to use a release agent on my pattern before pouring the rubber material. Any ideas for release agents? I have used vasaline on silicone molds before, is vasaline ok to use on the urethane mold materials? I can't seem to find out info from Smooth-On. They want to sell me their 'universal mold release agent'.

Help.

I've used Ease Release 500 with Smooth-On urethanes, and it didn't work very well. I've never used their Universal Mold Release, but it is what they seem to recommend in their technical bulletins.

With that said, I too would like to know what's recommended by other RPFers.
