With apologies, I am going to channel Ken_Adrian : where do you live? A big city nearby is adequate. Northern hemisphere? Was there any wrapping or straps on the trunk?

Yes, please post a pic here of the whole tree and the damaged spot.

In a general generalization: most tree experts do not recommend applying any product on a wound any more. Mostly we just let the tree heal on its own. It may be advisable to pare away rot or dead bark, but it’s case by case.

lol ...

zone is min winter temp.. so we need the city name.. to better understand the rest of the years ...

next time.. try the tree forum.. and possibly shrub forums....
