Crayola Air-Dry Clay - Sculpting?

It's kind of a stretch, but has anyone tried using Crayola's Air-Dry Clay for sculpting things like body kits or fiberglass speaker enclosures... or other things you can think to use it for?

I have a tub of this stuff, and I feel like I could use it for something. Ideas?

I'm not sure, but I can think of a couple things if it works ;) If you have some then why not try it out? I might have to pick some up...

the question is, why would you want to use it instead of tried and trusted putties?

My issue with it is the unknown shrinkage and well, I haven't tried it but I don't imagine it has very good sanding properties. The good thing about modelling putty is that they are easy to deal with whilst they are curing (that magic period when they carve oh so easily) and once cured, sand in a very similar way that the kit plastic does.

If it behaves like the air dry clay I have played with, then I should add that I don't like the "spring" it has when trying to sculpt it; I remember it doesn't behave quite like real clay.
