yep - you cant get spirals to settle down without softner; and you may need to just gently nick or peirce it (with a REALLY sharp (read: NEW) blade) to assist that little bit more...
Sorry for my absence - not had an awful lot of time to commit to the Dora of late and what little time I have had I've spent sanding the cockpit and engine plug little by little to ensure the fuselage closed up just right. Apologies for the blurry pics - tried lots of things to eliminate flash wash but these are the best I could manage.
