Failed Approach Graft on JBP

[DrBonsai]

After 4 years I separated approach graft on a JBP.
I cut half the branch in Dec. and the other half in Early March.
I thought all was well, but apparently it took awhile for the graft to die.
I removed the dead graft, however, there is a large ugly cut on the trunk.
My question is how to best treat the trunk?
Rewound/clean area, cut paste and tape ?
Just tape ?
Just cut paste ?
Nothing ?

Here is a picture of the "failed" graft site.
Any recommendations ?

I'd go with "Rewound/clean area, cut paste"

Carve it into an inverted tear drop shape. Photosynthate flows down the tree in the inner bark much like one would imagine thick goo to ooze by gravity alone - much like water in a stream. but in slow motion. Remember that sort of tear drop shape of water rushing around the stick you poked into the stream? It was much like a cross-section of an airplane wing. Carve that shape, then the phloem sap will feed the cambium all around the wound and it will close faster.

Graft a branch? Still an option?
