Folks:
Another vote for the English 'StarSpan' tissue: I've used the lightweight grade on several of my small free-flight rubber models, and agree that (a) it's easy to apply, especially if you put it on damp, (b) the colours seem resistant to fading, and (c) being polyester-based, it's tougher than the old 'Modelspan' that I've always understood to be the same as your Silkspan. The only thing I can't say is whether it goes brittle with age, as Modelspan used to after ten or twelve years - my free-flighters don't last that long!
All the best
John
