I just picked up a cheap pair of Mathmos glitter babies. I originally intended to either respray the bases/caps or just use them for parts as they were described as "badly scratched but work perfectly".
It turns out it's all surface damage to the bases and caps, nothing too deep. Has anyone tried polishing out scratches on these? If so what's the best thing to use? The first thing that springs to mind for me is Brasso, but I'm not sure if that will damage any coating on them.
