>>9786281Use a toothpick to apply small drops to friction points, it flows easily into small gaps and excess can be wiped clean. Move the joint around to get the gloss in, it needs a few hours to dry. If one application isn't enough, do another. I've used it on nearly every toy I own, it's barely noticeable unless it gets wet.
I am strongly against using super glue for joints, it's just too risky, but you can fix loose 5mm ports and posts with a very small touch of brush-on JB Super Weld. Let it dry fully, of course, before testing.
