Next up is reconstruction of any major missing bits and holes with epoxy putty like Aves Apoxie Sculpt. That's the grey stuff.
We then apply a barrier layer of B-72 to hold everything together for the next steps. Shiny!
Doesn't look so shiny anymore, but we can fix that with a wee bit more of very thin B-72.
And there you have it, one half of a bone restored in a few days time. Now we just make a support jacket so the entire thing can be flipped over and the process repeated.
