I had Winkler & Patrick plate some things with CAD plating. Ive noticed my scuff plates have gone like from sitting in a box for a few months...

I think Ill have to get them chromed.... Ive had them zinc plated previous, then CAD plated....

Rare Spares were talking about doing reproduction scuff plates for the LH/LX. May be worth checking on the ETA.

Sux when Ive outlayed $400 incl freight to have these zinc'd then CAD.... and they are still un-usable...

You seem to throw alot at this car then have to redo stuff Brad

Are you just "doing stuff" or asking questions beforehand ?

I have a mate that does aircraft grade Cad...I'll ask him why thats happened for you

[hanra]

I try my best to do all the work on all my cars myself. Because in the past exactly this sort of thing has happened... I have to re-do things when others get involved. Up this way you SIMPLY CANNOT GET QUALITY WORK DONE. So things I cant do myself usually have to be sent away somewhere afar... I had about 10 emails go back and forth between myself and Winkler Patrick before sending this stuff off for CAD.

Maybe these companies just think, well he is in another state... its not like he can come in here and whinge to me about this work...

Before the CAD, I thought Id give the local bloke a go with the Zinc plating and that turned out crap... Makes me consider buying my own Janes Plating Kit just so I know its done right.

G/day Brad
I found this with a google search.
I think the text I've underlined probably explains what has happened to your sill scuff plates.

A. Cadmium is a ductile, very malleable metal. The metal is soft enough to be cut with a knife, and it tarnishes in air. It melts at 321C and soluble in acids but not in alkalis. It is similar in many respects to zinc including Galvanic Corrosion protection capability but it forms more complex compounds.
High exposures Cadmium occurs with people who are exposed to fumes and when people breathe in cadmium fumes it can severely damage the lungs. Physical contact to cadmium is harmless. Still cadmium is one of the metals on the ''black-list" which should theoretically mean "zero-option". However, attempts in various countries - notably Sweden - to ban its use have been unsuccessful since it has been recognized that for certain applications there is no immediate substitute. Products and components of products used in aerospace, mining, "offshore" and nuclear fields where lubricity, ductility and resistance to hydrogen embrittlement is sought.

Whilst allowing the use of cadmium to continue for applications where there is until now no proven substitute available, still regulatory authorities are vigorously pursuing stringent targets on discharge limits.

In many cases this is surely causing platers to think carefully about the financial consequences of continuing to offer cadmium since new investment in effluent plant will be inevitable. Cadmium would be a good choice of coating material for parts in contact with aluminum. choice of cadmium plated fasteners for assembly of aluminum airframes in the aerospace industry.
Cadmium does have some specific application and capabilities but where alternate material can be used it is better to avoid its use.

And now a word from our sponsor

OK kidding... this is the word from my plater after showing him the pics



Looks like it has just tarnished ! Being that it is in FNQ the weather might have a little to do with it . I wouldn’t be surprised that if he were to use a mild polish like autosol that they would come up like new . Cad plating is able to be polished like other metals just as long as you are gentle as it is soft .

Thanks

Interesting. Ill try giving it a rub a dub dub with Autosol over the weekend.

So were these components originally Cadium plated

Surely they must have used another metal in the mix so they didn't tarnish as easily as Brad's has

It would appear the original Torana items were a little harder wearing and less prone to the effects humidity?

My guess is they were zinc plated not Cadmium plated.
