EDIT: I'm moving my webhosting around right now, if the photos break, I'll update the thread asap.
A little example of what a little bit of time, a good terry cloth rag and some aluminum polish can do to some hubs. Most of these are Campagnolo Record hubs which we all know had a very nice polish on them to start, but most of these had been sitting unused for the better part of 10-15 years. First post is the before shots, I'll put the after photos in the second post...
