Thanks everyone..

Dave this kit is holding together very well - with all the handling I have not broken any extremities yet! Everything fits together nicely. I have got a slight offset between the wing/horizontal tailplane which is odd given the way the wing and tail assembled to the fuselage. You can only see this from a front on view, and is only slight. I can see it, but I'm not too worried.
Mark, John, the edge tape is fiddly. It takes ages to get one piece started, to get the folds over the edges, but once started it goes down ok. It hides any roughness of the edges of the lozenge strips. The lozenge itself goes down very well, and is quite robust. If I was more patient I would make a paper template for each length - then with careful cutting the strips would sit perfectly up to the wing edges without need for further trimming. I have a few rough edges which are hidden, and some that show through when looking closely. I trim the lozenge after it has dried, one side at a time. The edges can still lift, so I coat with klear. Also, if I had wanted to add rib shading, I could have applied shading to the lozenge before adding the tapes, then that leaves the tapes clean.
Other WNW kits (the later ones) with lozenge come with pre-shaped and taped sections specific to the surfaces to be covered. I have yet to try these, but can imagine they will be much quicker to apply. The rib tapes are not separate so the shading would need a different technique.
Although I am not planning to weather this model as used or dirty, I will apply a matt finish eventually. I will use this to try out this coating by hand - the planking fuselage structure leans towards lengthwise brushing, and chordwise over the wings, so if there are any brushmarks they will be in the direction of airflow. I could spray the matt, but would need to mask off the engine and cockpit.
