Since, Mike (Kansas 914) brought up the question of the similarity in looks of yellow zinc to cad here is information for you to make your own informed decision. Keep in mind, cad plating has been banned in other countries and is very strictly regulated here in the USA due to the very serious side effects on health due to working with it.

What's so special about Cadmium Plating?

Here's a quote from the FAQ and information about Zinc plating, cad plating

"Without a special laboratory analysis it can be very difficult to nearly impossible to tell the difference between the two."

FYI - Jim at Yellowzincplating.com can only accept small items in batches, like bolts and such. I requested a price recently on some shock tower covers, split calipers, shift plates, 901 transmission mounts, etc.

Jim recommended I use a barrel processor or plate vendor.

Best of luck,

Hi. I thought I should create an account to clear up some confusion. I don't recall the exact situation with Dave's parts but occasionally I hear from a customer with a very large batch or parts with dimensions that exceed my capacities and I suggest they contact a larger commercial plater, as I tend to do "smaller" batches for car restorers.

That said, I get orders of 2 parts as well as batches or two or three hundred at a time. I can pretty much always tell from a photo or two if there is anything that I can't handle.

Study up at Caswell, they sell kits for plating. I have plated the 911 calipers and several other smaller parts for the 914. I bought a 30 a power supply on ebay that is the same one caswell sells that works great. I really like to do most things myself.

I like to sub things out so I am happy to hear more about these services. thanks, mark

Cadmium beats zinc in corrosion resistance. Being a former aircraft mechanic I like the stuff. However, I'm not a big fan of the adverse heath affects. I used to handle thousands of Hi-Loks (Cad plated interference fit fasteners) with little regard until I learned the stuff could kill you.

Hey 914ers,

Forget that CADMIUM can make you STERILE and is toxic. I have another reason to NOT go that way: Years ago, with my 1st 914, I rebuilt the engine and had ALL the engine tin CAD PLATED. It looked GREAT for a while, but then DID RUST! I was very disappointed!

Today, I can only think about POWDER COATING!! It's a very tough plastic coating and is darn near indestructible. I set my self up with a powder coat spray kit and an old electric oven in my garage, but there are those who can do it for you.

I can suggestion is a very honest guy: Barry in N.C., who is a site member and powder coats tons of Porsche parts in any color, at diehardcamaroguy@yahoo.com.

Best,
Terry
