I just got my collection out of storage and am having a blast putting them all back up. however the little guys are suffering from super floppy, spinning arms. I know all about tightening joints with clear nail polish, but judging by the way there's just a tiny peg in a hole (I think) for this, I don't think that's the best way to go about it. any ideas? I'm looking for specifics, especially from people who have done it before.
