Vacation is over. Back to work. I recently purchased some Instant Mold from CoolMiniOrNot and am thoroughly impressed with it. Below you can see the first piece I did.
It's pretty good! The only thing you need to be aware of is that air bubbles can get caught in fine details. Watch out for that. You can mitigate it slightly by the way you put the green stuff in.
You can also make two part molds. This is a little trickier. What's this image above? You'll see soon!
It's really simple to use. The thing to remember is patience. Don't peel the mold off while the GS is curing, and don't peel the mold off while it's cooling. Let it cool normally. I'm not sure if you can put it in the fridge to speed things up, but don't peel it off early or it will deform.
This is going to be a vital tool in my conversion arsenal. Anyone who does a lot of converting should have some of this. It's not expensive and opens new doors of conversion possibilities.
