About two years ago I bought a Lovik figure to add to my little vent family. It's a "living mouth" creation. I'm not crazy about LM, but I think converting it to slot jaw is more than I'm capable of and more than I'd want to pay for...so I'll stick with the jaw.
I believe I know how to paint the leather piece.
I've already replaced the ears and opened up the eyes a bit.
What's this thing made of? It's a rigid off-white material. I thought perhaps fibreglass...but I can't tell.
Anybody got any tips or comments or anything?

Those figures were cast in rigid foam latex....similar to what Jerry Layne and others cast their figures in. It is not built to last a lifetime--but some of those old figures hold up pretty well.

You can re-paint him in acrylic paint. Acrylic is latex, and is flexible enough to withstand the movement of that leather "living" mouth. You can also modify his features with some sanding, carving tools, papier mache compounds...or for something harder and heavier - you could use a two part epoxy compound.

Word to the wise: Bill Nelson modifies all of his figures with simple store bought papier mache' compound..that is probably like $4 or $5 a package. Remember, it isn't the tools or mediums you use, but the talent behind them.

That's rigid latex? Wow! Doesn't seem to have any give to it at all!
Thanks for the information, Matt!
