Electro galvanizing for 'spangly' muscle car parts
Q. Hello, I am in the muscle car & parts restoration on Chrysler products. Cars built from 65 to 74. Many highly desirable parts have the electrogalvanizing process with the so called spangled or sort of leafy finish. I do zinc plating achieving a more satin finish. These parts had not the highly glossy finish most plating companies do. What type of zinc plating caused the spangled finish & how may I achieve it?
If I would be able to produce this highly desirable finish, it would increase my business tremendously. If it means anything, most parts were of different thickness stamped sheet metal.

A. Hi Bill.
Without pictures you'll probably only get responses from car enthusiasts familiar with those models. Please try to get us a photo of the finish, and maybe a car that has it.
If by spangled and leafy you mean mottled in the fashion of a frosty window in the winter, I believe you can only achieve that by hot dip galvanizing, because it's a crystallization pattern from cooling.

If you just mean bright and shiny, bright acid zinc plating will do it.
