You don't need to grind off the old plating or prepare the parts. The plater will dunk them in his solutions and removed the old coatings and prepare them for the new coatings. Call a plater and talk about your project.
On my Technika, the frame was aluminum with corrosion under the chrome plating. The chrome was flaking off in places, etc. It looks like new now. I hated to spend the money, but in retrospect, it was well worth it.
This is very encouraging, thanks.
I have an email in to someone, who knows someone, who will know who to contact locally about places that do plating.
