I saw a YouTube video made by a French guy who used UHU glue to adhere the tissue/silk span. He lightly mister the paper, applied glue to all surfaces that would come into contact with the paper, and applied the paper, smoothing it and tightening it as he went. He then wet the tissue to promote the shrinkage and tightening he wanted. Looked like it made sense to me, but has anyone here ever tried this technique? I remember using dope on all contact surfaces, and when it dried then spraying it for shrinkage. Back then there was no concern about breathing dope fumes- how times have changed. I am open to suggestion as I re-learn how to build a nice balsa model. Thanks for reading this.
