If you get the Loctite 401 instant adhesive, the included tip is perfect for the job. My technique simply involved glueing about 2 inches at a time, while keeping the seam orientated so that the glue is pulled in by gravity. Immediately after applying the instant adhesive, wipe off any excess... Like within 5-8 seconds. I did get a little sloppy in some areas by applying too much glue and taking too long to wipe it off, but it's hardly noticeable. Once this stuff dries, it ain't comin' off.
What did you wipe the excess off with? Did you glue the whole thing or just the arms?
