I used turpenoid to brush the skin smooth. I first tried turpenoid natural but that did NOT work. It took about a minute to soak into the clay and then just made it gummy. Regular turpenoid worked great, quick acting solvent and it didn't soak too deep into the sculpey.
I like how it smoothed it out. Hoping to wrap this guy and start on the next bust. I will cast this guy once I figure out how to make a nice base.
