Finally finished it tonight... Though I had some problems with the decals. Thank God they didn't tear as Academy decals are sometimes prone to do. On the contrary these have to be some of the stiffest decals I've ever encountered. I used Revell's decal soft solution on them, but to little effect. This prevented me to highlight some panel lines over the decals as I planed. I tried that on the under wing roundels, but when I noticed they might tear I decided to let it be (see the last photo below). Also if you look at the close up of the fuselage roundel, you may notice partial white outline on one side. Unfortunately this became visible only after I applied it to the model so nothing could be done here. Though I don't know if I could manage to cut that out and preserve the round shape of the roundel anyway. Ah, well...
Apart from these few little things I'm generally rather pleased with this build. Always wanted to build a model of P-40, so this was good opportunity to do it. Tomorrow on daylight I'll take some more photos and set up the official ***Finished thread.
