I ve heard of modellers putting in plaster of paris inside vinyl figures to attach more weight to give the figure more balance.
My question would be how do you actually put the stuff in?? Do you mix them up with water before stuffing in the stuff? Or do you pour in the plaster into the figure before adding water?
How do I prevent the plaster from 'cracking' inside the vinyl figure after it s dry?
Im confused.......... #:-)

This is really pretty simple. Most vinyl kits have a separate lower torso. Built the legs, making them water-tight . Fill with water to a bit below the waist. Pour this water into another container, then mix in plater of paris. Pour the plaster mix back into the legs/lower torso -- you may have to poke it a bit with a stick to work it down and get out the bubbles. In a few hours it will be dry enough to continue with your build.

If you slop a little plaster on teh ourside of the legs, just wipe it off. After it dries, you may need to go back with a bit of soap and water to clean up chalky residue.

I don't think you need to worry about the plaster cracking, but if it does -- who cares? -- it's on the inside anyway!

If you put pins in the figure's feet for attachment to a base, you can put them in either before or after the plaster is put in. If you put the pins in before, make sure you seal the holes well or it may leak and make a mess.

Even though I only have painted one vinyl figure (hmmm...is PVC vinyl? I don't know...) I haven't tried that yet... But the box that the model came in with had instructions. It said :"If figure does not stand, fill with plaster and let dry..." I think it says you need to fill vinyls with plaster, they're hollow anyway, so I think it's meant to be filled...

By the way, thanks for the URL about the anime-models, Basturk...

If you don't make the plaster too thick it will flow easier. Thinner mix takes longer to dry but at least it will fill all the tight spots and reduce the number of air bubbles.
