As I said in the article, I used a product called "Polyspan" light which is kind-of a tissue-like substance that has heat-shrink properties when a heat iron is applied. What you do is to cut it to approximate size, place it on solid areas and moderately mist it with a water spray bottle to hold it in place. You iron over that to remove the wrinkles, then quickly cover with dope to hold it in place. Add another cote or two, use a coat of filler/primer, then final paint.

I used the Radio South polyurethane paints in two parts. All of this added considerable weight. My Simla wing for example was built with contest balsa and was very light. By the time it was painted, it wasn't light any more, (I probably over-applied the paint to make things worse because I had a couple areas where the paint ran some. BTW...the RS paint gave a beautiful finish that looked good in the magazine article.

I believe that just the polyspan and dope wouldn't be that heavy if a light filler and final paint coat is used. The Polyspan tissue/fabric material I used was the easiest material I have ever worked with in terms getting rid of wrinkles...there isn't a wrinkle anywhere...even in compound curve areas around the nose. I recommend it for those who might want to try fabric/dope.
