Coating of auto parts with a ZINC PHOSPHATE finish.

Anybody have the name of a business that does this type of finish to metal?

Hi 4,
Check out Detail Plating by Steve Gregori.
He does various plating types that were used on our cars.

Zinc (light) and Manganese (dark) phosphate can be done at home too.

This is the phosphating process…. a heated bath (200 degrees) in a stainless steel or glass container.
It happens to be the darker manganese phosphate, zinc phosphating is the same process with a different bath.



Prepped and after the phosphating.

Alan did you purchase the plating kit thru Eastwood or another place?

Hi dm,
I'd like to say "sure", but right now I'm just doing my own parts plus some parts for a couple of friends.
Sorry; if that changes I'll keep you in mind!

Hi AZ,
I buy my zinc plating and black oxide supplies from Casswell and my zinc and manganese phosphate supplies from Lauer Custom Weaponry.

check with local gunsmiths and DIY gunsmiths. a lot are into parkerizing, which what you want done is called.

My tanks havent been up in a couple of years but I used to do it all the time.

Alan.....thanks for the reply ......I have used Steve to rebuild a booster. I forgot he did all kinds of other stuff. I think he prepares the items and sends them out to third party ...if I recall ?

I have a hood latch assembly from a Camaro , it's been sandblasted to remove the rust . All clean and pretty.

Soooo.......did GM use Zinc or Manganese on their hood latches ......I had heard they were manganese ....but most people won't notice ?

Rowdy Rat

For a first generation Camaro, you're probably looking at zinc phosphate. The latches and hinges/springs tended to be much lighter than anything on a Corvette. For Corvettes (1969-1972) it would be manganese phosphate. I would say 1968 is similar, but it wouldn't surprise me to see some cars with zinc phosphate plated latches.
