Spark plug sheilds
 

Can anyone please tell me the correct plating for the 69Z spark plug shields and where would you recommend to send them?

Re: Spark plug sheilds
 

They are common Zinc plated.
Any plater can do them.

Ed, email this guy: [email protected] He does this work on the side and is a good man. I bought and had a few things done by him. I think his work is real nice. His name is Brent Roby. His number I believe is (614)471-4883. Sam

Zinc is the ingredient for galvanizing.

You need a galvanizer, not a plater. Most platers don't galvanize.

Technically, galvanizing is not plating as plating refers to an electro-chemical process. Galvanizing is a "hot dip" into the zinc alloy. I believe the spark plug shields were stamped from galvanized sheet. That means the edges are raw steel, but since zinc has a tendency to heal itself, the edges don't rust right away. Pretty tought to duplicate the original spangled galvanized coating by regalvanizing the finished part. Galvanized usually has a very bright appearance when new and gradually dulls and grays with exposure to the atmosphere and its' self-sacrificing nature.

Zinc plating is, however, a plating (electo-chemical) process and does not have the spangled appearance. Big difference. https://www.yenko.net/ubbthreads/imag...ns/scholar.gif

Did the originals have the little screws, or were they spot welded?

They should have a screw,you.

So, what is the recognised approach for plating or dipping process to restore a set of originals?

Thanks for the advise
