Howdy
I've got an old Cinelli stem I had to put back into use for the clamp diameter, so I could do a bar swap.
The stem has some nasty gouges and I'd like to glean some advice to remove / reduce them.

My thinking is to start with 120 grit emery clothe, and work my way to finer grit until it matches the rest of the finish.

Before I completely bugger the thing up, anyone ever do this right? If so, how?

Thanks.
