You mentioned cleaning the glue off the fuselage tubes was a real pain. Have you tried rubbing the glue off with a rubber sanding disc dresser? If you're not familiar with these its a rubber bar about 1 1/2" square and comes in various lengths (see picture below). Its used to clean up belt sander belts that have caked up with residue. I got mine at a local hardware store that sells professional sanding tools. This works like a dream on excess Stewarts glue anywhere on the fabric and on fingers too. If the 3M glue you're using is anything like the Stewarts glue it should work great, just needs a little rubbing. By the way - I've painted my Kitfox with latex last winter per the weinerdog.aero method and I couldn't be happier with the results. I rolled my primer and top coats on with a nylon foam roller and never did use the new air compressor I bought. The final coats of black and white trimix my paint scheme came out glossier than polytone and I didn't actually need to spray anything. The yellow I used was not that glossy (more like polytone) but it turned out to be a great look anyway.
