I have been enjoying my stickerless cube very much since I got it, and it's never failed me. However, on a drop, the cube fell on one of its corners, which promptly exploded. I managed to reassemble the corner properly, but now a slight bend from the impact on the plastic has caused white lines to appear on it. I am getting a ZhanChi soon, but for now, I'd like to know: is there a way to hide the white lines, or is my cube beyond salvation?
