I went and looked at mine. First time in years. It used to be shinny. It doesn't look like chrome. It is pot metal and plated. The plating looks like the same material that was used on the spokes of the rim blow steering wheel. I know the wheels can be replated. I would guess that latches could be also. I will need to do mine. Maybe someone has done this and knows how and where to get them redone.
