...yes, that funny looking cloth near the formers is drywall tape , yes , drywall tape...
Re that drywall tape, it is fiberglass with a light tack to one side to hold it in place. I have used it and it has worked well for me. It does take some filling to smooth it out, but no more than full weave glass cloth. How did it work for that application?
