Modeling clay

[Big Messer]

Maybe is ancient news, but new for me. Found this air-drying clay at Hobby Lobby. Dries real hard but easily sandable with coarse sandpaper or a sanding drum with a Dremel. Added new coats or pieces will stick over already dried pieces. Thin coats dry fast (within hours) while thicker applications will take longer. Will shrink when drying but I just add more after. I don't foresee problems painting with acrylics but haven't tried yet.

Most art and craft stores stock this sort of clay by a number of manufacturers. Quite good for making scale loads for trucks and other stuff.
