Spent a long time looking and admiring other peoples work really enjoy the full strip down and rebuilds. Does anybody know a good platers for the gold effect zinc plating ? I read threads where people are talking about £20 for a bucket of small brackets and fixings but the places I have tried were so expensive its cheaper to buy new from a main dealer. The parts have been prepared by soaking in vinegar to remove any rust and old plating then any pitting polished out with wet and dry. I would be glad of any help with this as some of the engines I have seen on here look fantastic and I just don't have the room for a DIY set up Many thanks for any help Graeme Johnson

Thats cadmium plating rather than zinc i think your on about . Google image search to check if thats what you mean. Your best bet might be to do it yourself . Frost restoration sell various kits and from what i gather you need no more room than a large bucket .

Thanks for the quick replies yes I think the correct name is zinc passivated I have looked at DIY kits but you seem to need a tub of hydrochloric a tub of distilled water and a tub of solution to give the colour as well as the plating bucket which I don't have room for I would just like to find a reasonably priced plating firm and some advice on quantities if they have to fire up a machine it may be more cost effective to have a few bits done at once. I have seen loads of adverts online but would rather hear from someone with experience as I think a lot want large scale commercial work not small jobs Thanks for all the help Graeme Johnson

It's yellow passivated zinc plating. Paramount platers in Ashford are reasonable with their prices. You can also get a blue passivated finish,basically bzp finish.

I did try it myself once. Not as easy as it sounds. Was tough to get a nice smooth finish and didn't get much done before the solution got tired and I gave up

Johnnybravo thanks for the recommendation I will google them and get in touch for a quote the parts are like new polished steel so its just the plating I need doing I have seen the different finishes and colours but the gold/yellow is nearest to factory original David I have seen the battery charger trick but two days in the vinegar then a brillo pad is working fine mind you its all under bonnet stuff and the cars been garaged all its life so its not that rusty just dull Thanks to everyone that's replied Graeme Johnson

I used a chap in Coventry to do yellow passivating, came out very well. Mine was a bit pricey, which I think may be down to there being fewer places in the area doing it - I know a guy in the north east who had a lot more than I did, for about half the cost.
I've got a kit from Gateros because I like doing these things myself, but as slater said above, it's hard to get a very good finish. I put that down to not being able to have the kind of cleaning and stripping solutions that an industrial plater would have access to, though I'm sure some of it was because I wasn't as thorough as I should be. The process is to nickel plate first, then clean, then clear passivate, then clean, then yellow passivate. They also did some other colours. Actually as I write this, part of my lack of success is down to the power supply for the initial nickel plate - I just had a basic supply (part of the kit) with a spring to act as an adjuster, like on those cheapo arc welder kits. It's hard to get the correct current for the first stage, and if the nickel plate isn't clean and bright, then the passivating won't be either.
I use citric acid most of the time for rust removal - I tried vinegar but didn't have much success. I've done electrolytic as well, which often works well.

I think a friend of mine has been getting odds and ends done by these people - He's away at the moment and I cannot ask him what he pays but they do small batches and appear to cater more for "enthusiasts" niphos.co.uk/

I've used them for chrome plating before, that was very good, haven't tried them for this though. I do remember having a chat with them a year or two ago at the Elephant show as they had a trade stand there with some examples of their work.

I did it on a calliper, and it was spotless after.

Niphos does look interesting as well like all plating the finish is in the preparation the stuff I have is ready to go for this type of finish chrome would need a lot more smoothing and polishing but this is mainly for corrosion protection even brand new brackets that I have been buying from Mercedes-Benz have various forming marks in the metal itself. The rust removal ideas are all interesting the vinegar is working fine for me I did step up to a type of trade only drain cleaner by way of an experiment on something that was very rusty health and safety would have a fit it shifted the lot but the pitting would have taken ages to buff out and a new bit was only a tenner from Mercs so I just replaced it in the end Thanks to everyone that has taken the time to reply

If there's pitting involved, passivating won't be much better at dealing with it than chrome is, just less expensive. One of the issues I had with my home plating kit was when an item was pitted the pits come out black, which I'd assumed was down to being unable to clean well enough. However one of the parts I took to be done last year was also pitted, and it's no better even with their proper acid.

I think these are some of the parts he had done at Niphos - Steering shroud Fuel pump and accumulator bracket Area's of corrosion that are not smoothed out just come out as dullish patches.

Basically, just do whatever johnnybravo says and you end up with bits that look like this:

I bought one of the home kits last year to do a few brackets etc
It works pretty well as a basic kit, but it can be fiddly and time consuming to end up with a decent finished item
Any pitting will obviously not look quite as good as smooth/smoother metal, but that can be mitigated to some extent by moving the part around during the process, so that different areas of the part are angled towards the anodes and so receive a decent coating of zinc
Preparation is everything, the de-greasing and de-rusting phases are the most critical parts of the process, the plating and passivating bit is actually very easy once its all setup
Basically you get out what you put in, any really rusty stuff will come through with a reasonable finish, but will only really be good as a reasonable looking corrosion resistant coating, if you want the factory fresh look, you need to start off with a decent item to begin with

I've used S&T in Yate a few times and found them very good. They manually polish out any pitting and I've had a damaged part repaired by them prior to plating. stchrome.co.uk/
