Hello guys, I got a problematic DOTM Shockwave on me, where the right arm simply won't stay in its bicep joint after a few twists. If left untouched, it's fine, but any attempt to pose it will push the plug out of the socket. I think I need to add something at the opening of the socket to hold the plug in place, but I'm not sure how to do that. I've tried a few coats of Future Floor Polish and Nail polish to no avail. It's not a deal breaker for the toy, but I was wondering if there was a way to fix it. Any help or suggestions would be greatly appreciated, and thank you!
