Thanks, Dave, after posting my query but before reading your reply I actually had some time to go out and fiddle around with the Tamiya paints. I was using a 50/50 mix of product and X-20A thinner, with 15psi in the Badger, and was getting pretty good results. So I was glad to see that was very close to your working specs.
And Zac, everything on my Nieuport so far has been brush-painted, all the cockpit components, as well as the seams, which I've been hitting with Tamiya Liquid Surface primer. I haven't tried brushing the Tamiya acrylics, but after reading your reply I'll have to give it a try! (and I haven't forgotten about scanning that Nieuport rigging diagram, I just need to get my wife to show me how her scanner works :-)
