RE: Silkspan and dope
Silkspan and dope look great! My black fused yellow winged Keith Rider R-5 'Jackrabbit' is over 15 years old and it still looks great with its silkspan and dope finish, (IMHO)! There's no mistaking a doped finish. Very light finishes can be had with it. But... it is fragile. That's why I use Koverall. One method can be just as difficult or easy as the next. This Fokker DrI middle wing was covered with one piece of Koverall. This Piper Super Cruiser fillet was formed by one piece of covering each side. This is much easier to obtain with Koverall (or similar polyester fabric methods: Nelson, Stits, PolyFab etc).
