What does one do about the red plate on the frame head tube when repainting the frame? Do you remove it then somehow rivet it back on? Do you just cover it and paint around it? Do you replace it with a brand new one? In this case, you'd have to restamp the original frame number, which seems somewhat disingenuous since you would thereby have a "matching" bike if you didn't have one to start with. None of these options seems particularly appealing to me. What's the lesser evil?
