Customizing becomes a money pit when you constantly buy whole figures to harvest only one or two parts. Use Oyumaru to save a ton of money by replicating all those bits and bobs.
Oyumaru is a thermo-plastic (maybe it isn't plastic but let's call it that) from Japan that becomes as soft as clay when heated, then solidifies into a hard rubbery material when it cools.
You can get it off places like Amazon for about 8 bucks (12 sticks, 2 packs of 6). It doesn't look like much, but it's completely reusable and you don't need much for small items like hands, weapons, etc.
Here are some things I made by stuffing some Oyumaru molds with Apoxie Sculpt.
There's no need for a release agent, the AS easily pops out after it hardens.
This is the fastest way I could think of making the mold.
•Press the foot into the Oyumaru, making sure some of it squishes into the peg hole so you have a guide for drilling later.
•Engulf the foot in it, making sure you don't trap any air bubbles or water.
•When it's cool, make a clean cut along the sole of the foot to create a flap you can lift to pop out the foot.
•Stuff the mold with your preferred sculpting material, close the flap and squish it around a little to make sure it's holding the right shape.
•Use string or tape to keep the flap shut, but don't make it so tight that it deforms the mold.
For a more traditional/professional mold, make it in multiple pieces.
Here the process is about the same, but I made a separate piece for where the peg hole is. Also, I made the cut along the top of the foot.
Try to make the cuts in places where it's easy to remove the flash/mold lines.
It's a straightforward process, and you'll get better at making more effective molds the more you practice.
Note that the AS pieces might be tacky when you pop them out, I leave them alone and the tackiness goes away. I'm guessing it just needs that little extra time to cure completely after taking it out of the mold.
Here I made a mold of a wrestler head I sculpted.
•Engulf the head in Oyumaru, leaving the neck area open.
•When that cools, you can stick more Oyumaru on the neck part to make a separate piece you can pull off. That way you have an easy way to stuff the mold with Apoxie Sculpt.
•Make a slit so you can pop out the head.

For this head mold I didn't make a "neck plug" because I wanted to see if I could swish around some liquid latex in there to make a stretchy removable mask! It didn't work because the latex didn't completely cure, however, the parts that did cure looked good. I'm not sure how to force the latex to cure, I guess I need to use much thinner coats at a time.

The bottom image is a push mold of the face area, same idea, I wanted to make a latex piece of just the face.
Try this to make gross skin masks for Marvel's Chameleon or some horror figures.
