Doing my first ever component polishing job some years ago, with too much pressure from a Dremel, I sanded the Shimano logo right off one of the levers of a first gen DA brakeset......
Every time I encounter those once nice old levers in my stash, with a polishing job half done on it, it breaks my heart.......
I would have just tried to find a buy another set of levers to replace them, but I can't seem to find any out there.....
