Is the seat post half shiny or half dull?
Campagnolo Super Record seat post from an online auction site. THC advised me on technique and let me use his supplies. If I were not so impatient to shine this lovely component, I would have taken a before photograph. But sometimes you just can't wait.
Imagine a seat post that looks a lot the this one but less shiny and you've got he idea.
Take a mental picture of this bike (or just take this picture). Someday it will have a matching fork, it will be clean, it will have wheels, cranks, seat, derailleurs and the rest.
The word Campagnolo was barely visible before polishing. I thought it might be completely gone after sanding but it magically appeared with greater definition.
