What sort of plating are the wishbones push rods nik link bars etc etc covered in.

Thanks.

I'm sure their cadmium plated, but - IMO - critical components like this should be electroless nickel plated.

technically Bright zinc passivated (as per "BZP" bolts), as passivating is only the process....

Thanks Fergus

Both processes are passivating (ie, they surface treat the material so as to inhibit the material's chemical reaction to other compounds to which they are exposed (in our case, mainly water and air)).

Personally, I favour Electroless Nickel Plating over other platings, because many other processes cause hydrogen embrittlement unless the component is 'baked' almost immediately following the plating process.

I don't trust any plater to really understand this in a racing component context, so I specify Electroless Nickel Plating - which is risk free process and (incidentally) looks a lot like unpolished stainless steel, which is nice.

Is there a price difference? Any reccomendations as to someone who can do it?

One of the upsides of both of us living where we do is that there isn't a better part of the country to live in to be near the very best 'platers'.

Depending on the passivation material, you can get whatever you want, virtually any colour, any gloss level; for example, nickel plating can be got from matt to full on bright, simply according to the phosphorous content utilised.

If as I suspect it's aesthetic and you want them to look that nice pristine & fresh gold colour they came out of the factory with, then that (zinc based passivation process) can be done, but the only question you perhaps should be asking yourself is "OK, they've got a bit tired looking, I can make them LOOK like new, but I am actually going to be simply dressing up a sow's ear to make it look like a silk purse?; is this tired looking component reminding me that it's now lifed out and it'll still be lifed out even if it no longer looks it?"

I'd suggest that by all means, get the 're-plating' quotes, then compare those with the cost of new components and make your decisions accordingly.

I don't know about any price difference, but I use GB Hard Chrome in Basildon - 01268 727504.

Guys
thanks for the replys.
Splitpin getting the wishbones shot blasted then getting them crack tested before I proceed only good thing about my winter project is ok it's a 04 car never been on slicks and hasn't seen any kerbs so hasn't had the loadings and abuse that most of them have seen!!
