I visually completed the right side fabric piece by gluing all around the vertical stabilizer and shrinking with the heat gun and iron. I went over all the fabric with the iron at 130 C and will later do it again at 160 C. I still need to finish gluing around the top stringer and forward stringer, but will need to re-apply some glue in that area as I believe I already activated the existing glue with the shrinking.
