Followed your directions exactly. Getting the metal corner bead in was a pain, but I did manage to. I had a difficult time with the metal in one area, couldn't get it in flush, so there is a gap. I decided I would have to live with it and attempt to conceal. A relatively short term fix to a bathroom that needs to a major redo.
As discussed in the previous post, I removed the mold that was on visible, applied silicone caulk to the areas around the tub where the prev owner put grout.
Closer look at problem area.
Still have to do some sanding and one more coat of mud.
Again, thanks for your time
