A few shots of before and after of my attempt to speed the healing of the sunburned horizontal limbs from summer 2013. I just brought over an adjacent smaller branch and, sometimes after scrapping the undersurface, nailed it to the injured limb.

Another still. I have the big vertical pulled down with wire and that blue twine.

As they grow, I will graft the leading branches of the donor wood into the viable bark that is down-branch from each wound.
The first two that I showed won't need it, as I think that they will look pretty cool intact, but the third, in the last two pics, will eventually need to have the donor branch removed as it messes up the symmetry of the tree and was only kept for this use. I made certain that there is cambium contact where the donor branch first makes contact with the injured limb.
Any consensus on merits of treating or coating the exposed wood?
A couple of those pics showed the progress in healing that happened last summer, 2014. THer is about a quarter to half inch of dark brown growth beginning to encase the wounds from the outside in, healing by secondary intent. But it's got a loooong way to go, even if my grafts take and eventually fuse with the underlying branches as expected.
