Magic Sculpt Curing process??

[SanShouXMA]

I have a Mattel General Zod figure and need to add a Hot Toys neckless joint to it so that I can attach it to a Goemon body. The thing is that the head is hollow and I need to fill it in order to put the neck joint into it.

Question here is:
I know Magic Sculpt air cures. Will it still cure if it's packed into the head? If so then it will not work in this instance. Should I use some JB Wells to fill it?

yes... theres a chemical reaction when you combine both part A and part B of Magic Sculp. It'll harden within 2-3 hrs.

Yep it's all I use anymore for minor sculpt fixes and tweaks
