Bob, You are right. If you prepaint then rig, when you cut the excess rigging off it does take a spot of paint off. This is much easier to feather the edges for painting than trying to remove the superglue from bare plastic.
On some models I will paint the underside of the top wing and upper surface of the bottom wing then rig the model. On the Halberstadt I used in the news letter I painted the model after I was finished rigging. Since the model was a dark grey I just painted the rigging to.
Hope this made sense.
Not only your explanation, but your plan of attack made sense. Still, I'd be nervous trying to paint in-between the wings!
p.s. I like the PV-1 turret-cover idea- might have to take you up on that one. (And for you "do it yourselfers", yeah, I know I could, but for $5 I'd be tempted to let Mike do it for me.)
