Depends how it broke, I have welded the one back on the pipes with no visible blemishes and a little silver paint on the weld itsself. If the tab broke against the back of the chrome part it will blemish. For some reason the pipes on Wendys bike used to break heat shilds loose, I never did see any reason why.

I learned all I need to know about life by killing smart people and eating their brains.
