If it was chrome, best to take it to a chrome plater to have them reverse the process and strip it, if it's paint then more nitromors or a lot of work with a DA/sander otherwise find someone with an acid bath that can dip it for you (SuperbikeDan has one)
.
Looks like chrome to me though so I find a local plater and have them do it, shouldn't be too expensive or take too long.
