i donno if it matters as far as i know everything comes off then nickel then chrome seen a ff he chromed he brought me in to see the finish it was the nuts i know he can strip chrome cause there was a harley d guy picking and dropin off some stuff and he collected some stuff had been stripped bare he said they shouldnt have been chrome in the first place looked real clean to me , i reckon he can do whatever you want and tell you what prep you need to to if any , the only thing he did say was die cas stuff could come out pitted due to the material , its guarenteed for a year as well
