I got some Army Painter super glue activator and I was initially a bit skeptical but should not have worried. It works a treat and after a few trials I have got the technical sorted. Its great for glueing those pesky arms that are tricky to pin. No worries just super glue, hold together (the hard part) and then spray. It really stinks and I would advise some fresh air straight afterwards.
you can quote me but "its the best thing since sliced bread" ;-) Yeah no more curses and worse when trying to superglue.
