This is a bit of cross-polination; I've recently begun using Tamiya Polyester Putty for my Gundam modelling, and I was wondering if it would work just as well for /16 figures and the like. Polyester putty is a two-part material (like Milliput and other epoxy puttieis) only, it's more liquid, and after mixing it dries quickly (60-90 minutes solid). I was wondering if it could work, or if it's too brittle (or just won't stick to the PVC plastic of figures) if I use it to sculpt new parts.
The main appeal I have with Polyester Putty is that it's like paste--your slap it on, wait for it to dry, then carve/sand to shape. Woks fine for Polystyrene plastic (Gundam models and the like), but not sur abotu 1/6 figures.
