What kind of clay to use on ponies?

[StarDragon]

I'm thinking of using sculpture add-ons to my customs like wings, horns, and such, except I do not know what kind of clay to use. Any suggestions and pictures/examples of what you use? Thanks for the help!

P.S. in case some clays work better on certain generations than others, the ponies I have to customize right now are G1s.

A lot of people use super sculpey, or epoxy.

This stickied thread, at the top of the Customs Forum, should be helpful to you.  I use Apoxie Sculpt and Apoxie Clay.  Good luck!
