I want to remove the side-caps from my Butterflies so I can paint the inside of them. What’s the best way to go about doing this? The first thing I tried was to stick a knife in them and pry it off (like this kid) but that only resulted in a bunch of mangled side-caps (and some broken knives!) I then tried pulling the two halves apart and sticking a small paintbrush through the hole to pop out the sides–which worked great, until I realized that the axle is apparently Hercules-glued into the blank side of the Butterfly. I spent ten minutes trying to yank it out with pliers, but to no avail.
Does anyone know a way to get these side-caps out without damaging them? Any help would be greatly appreciated!
