Alright, basically I just want to open up Mirage's shoulders/front fenders and slop around some nail polish, because his shoulder joints (backward/forward) are really loose right now. How straightforward is it? I mean, it looks like there's four screws holding it together, but is there anything else to watch out for? Also, what's the best brand of nail polish to use for beefing up joints? The stuff I use seems to rub off really quickly.
