Diabolic Wave
Ever heard of varnish? Technically, when I had my good smile figma's [oldest one i got was Haruhi], it breaks, and when it breaks, I use some varnish, paint, and a fine blade. I had sets of acrylics to cover and patch it up, and the blade to make it like it's original again. But trust me, this is a painful process to work on, it's like re-crafting a figma from scratch.

Thank you for the suggestion. I'll probably use that as my last resort :]
