I've been working on a re-haul of a 'rejoice' Breyer horse. I looked everywhere for something I could sculpt with that I wouldn't have to bake when it was done. I eventually found
Apoxie Sculpt. It dries rock hard, is about as harmful to your skin as salted peanuts (i.e. nothing will happen unless you have the bad fortune of being allergic to it) and has about an hour of working time. Perfect, right?
Well, except for the problem of
sticky. This stuff sticks like crazy: to your tools, your fingers, your counter,
everything. Their safety solvent will temper this a little, but eventually I found something even better...
(pause for dramatic effect)
Super Sculpey.
Super sculpey can be mixed in up to an equal portion with part A and B of Apoxie, and gives you a mule-like hybrid that combines the best of both sculpting compounds.
Pros: Adding a third part sculpey almost doubles your working time, gives the material more elasticity while working it, and
cuts the stickiness almost in half. It's still tacky, mind you, but nothing like before. Something in the Apoxie kicks the sculpey to cure, so you don't have to worry about baking it: leave your new handiwork overnight, and it'll be rock hard by morning. Super sculpey is usually marginally cheaper, as well, so this stretches your dollar a bit more.
Cons: you may have a slightly harder time bonding two pieces together, so if you're planning on using the Apoxie like glue, this probably isn't the best mix for you. It still bonds up fine, but will separate if you accidentally nudge it or something while it's still wet. I've not had problems (yet?) with bonded seams once it dried, notwithstanding the extra effort in establishing those seams.
