Swanny Great article, as ever clear and concise with excellent photos.
I'm currently using your technique on the glass house on my Ju287. Due to the large number of individual panels on this canopy, I tried running long strips of tape from top to bottom along the edge of each row of panels, and then from left to right.
This ensures a straight line along all the panels, I've always been prone to wobbly masking!! I then snipped out the sections of tape covering glazing bars, leaving a fully masked canooy with no wobbly edges!!
Just a variation on your technique.
