Paul, I use straight nitro cellulose cut in MEK. I'm not into plastics for hardening natural wool.

I'd be interested in what people are finding that they have to do to prepare them for any kind of fine voicing. Are there sections that needs more hardening/needling? If hardening, what chemicals are working best? How much? If needling in any general sense, where and how much?
