Cad Plating
Has anyone found a DIY cad (or cad-like) plating system to make hardware store fasteners look Porsche-worthy and/or to renew all the gold/yellow parts Porsche uses? Or, has anyone found a good place for plating in the San Jose area?

Check your phone book, a year ago when I was looking to get some stuff done my AZ phonebook had a few for me to call - prices are quite cheap if you price by the batch and not individual parts.

Tom - Although not in San Jose, Burbank Plating will replate your old stuff, or whatever pieces you send them. Otherwise, like Sam said, call plating shops in your area, and ask if they'll replate old automotive hardware/fastners for a rebuild project. For about $100 you should be able to replate (in yellow zinc) more hardware and fastners than you care to count and categorize. Yellow zinc is the factory finish, and is cheaper; while cadmium plating offers better protection, but is more expensive. Keep in mind that any hardened fastners (grade 10.9 and up) will need to be baked after plating, to diminish potential hydrogen embrittlement issues. The shop should be familiar with this, but you will need to point out the hardened stuff to them. The other alternative is, don't replate the hardened stuff. I just went through this myself, and replated hundreds of hardware pieces, to include all non-critical engine fastners, brackets, pulleys, heat shields, etc... All for $135! The real PITA was categorizing, and creating a list of all the bits and pieces. The stuff looks much better now - like new!

I believe some of the hardware in older Porsches may have been cadmium plated, but our vintage cars used yellow zinc. Yes, all that goldish/yellow colored hardware is yellow zinc plated. Cadmium plating offers superior corrosion protection, but is a more expensive finish. Cadmium plating is a dull silver/gray finish, and is more commonly used in aerospace, military, and other specialty applications.
It is my understanding that tin-zinc plating is a new alternative to cadmium plating. It reportedly has superior anti-corrosion properties, while being more environmentally friendly. Esthetically, yellow zinc is shiny and gold (while new), is the original look in our cars, and its corrosion protection is adequate for the application. That being said, there is nothing preventing you from using cadmium or tin-zinc plating other than personal choice, looks and price.

A friend and I purchased the Copy Cad from Caswell and it works fantastic. We bought the 1.5 gal kit. You can plate about anything, including regulators, brackets, bolts any conductive component.
Even surfaces you don't want plated you can coat it with plastidip (i.e headlight linkage) With this kit you get the degreaser and chemicals and the power supply. If you want to plate large surfaces you will need a power supply to carry the current load (adjustable is best, some of the solutions in the literature are kinda low tech simple). I would most definitely recommend this setup for any Porsche owner who wants authentic looking components. If it is fastners you are looking for try this link. www.eagleday.com.

Cadmium is nasty stuff, most of the people who work with it have died off.
It's a dull silver color, not that yellow you see. I used tio have a source up here, but the last time I used them was for some brit stuff about 10 years ago.
I doubt it was ever used on 944s, but I could be wrong.
