Greg, my theory is that when you are looking at a reflective surface what you see is what it is reflecting, which on a good day is blue. But really the gloss part is the most important and I just happen to have a lot of Ford Engine Blue from when I bought the paint stock from a hobby shop that was closing.
I have Italeri kit 091 of the An-2, and I thought maybe it might be a different kit, but the parts are the same. That canopy is a nightmare, but then that's how Antonov built it. I tried a test fit of the injected parts and it seems a workable strategy is to attach the two lower parts to each fuselage half first, then add the top part. Definitely need masks. Does anyone make them using them Tamiya type tape?
I probably got that little front triangular part a little low but given the acute angle a little white glue should hide that well enough. It doesn't look to me like it is shaped quite right, and in any event there is an angle to the main canopy that it does not conform to and if a bend is tried there will probably be stress marks. Might be better to use it as a pattern for a replacement acetate sheet. Given the scale I don't know if it is worth it. These pictures are a lot larger than the model, and the main canopy is just resting in place.
The Pavla vac canopy does not look good at all, and the resin parts look pretty rough to me, in the pictures I found on the net.
Thanks for the tip about DDG.
Here's a picture I found on Prime Portal. Looks like the plastic part is too long and should only come up to the frame on the upper canopy, and the rest is sheet metal after the break. Hope this isn't TMI, but once I get going on research...
