Back to masking... I use the painters "Blue Tape" and that works fine for these models. The Tamiya tape is very nice, but I don't think you need stuff that good for the scale of these models. The alternative is to cut strips of paper, which I did when the color was hard to match, and now I prefer this method.
Here is a photo of 2 Me109's the Grey one has painted canopy and the tan one used paper:

PS: The grey one has had the wing repaired once, and the tan one still needs repair and a totally new wing!
