Thanks!
The nose was actually easier than I thought it would be. I sprayed on Tamiya black, then cut strips of masking tape that were 4 inches wide (to scale, of course) with Tamiya tape. I put down the first stripe, then stuck on a small piece of tape on either side that was 4 scale inches where the yellow would go, and used that to align the masking for the next black stripe. Once the black stripes were masked, I painted on the yellow, and then masked it all off to finish the painting.
The Tamiya tape went around the curves quite well, I thought. Having small guide strips of the correct width around a few places on the cowling made alignment much easier. If you look close, you can see the first stripe aft of the spinner is about 6 inches... messed up my measurements a bit.
Still- it was much easier than trying to get the decals to fit! :D
