Chrome parts

Postby Islander » Sat May 11, 2019 3:07 pm

Is it better to re chrome old pitted chrome or replace with new chrome parts? ...From a quality perspective rather than cost or time....my impression is that re chroming the old parts - assuming that the re chroming is done professionally - the end result will be better (better metals used in the past etc)

Hello Islander,

if it's mazak castings then if they are pitted I think that they are pretty much scrap. Pitting would need filling before any polishing and plating is done and I think that it's not a metal that could be welded satisfactorily? If it's steel or brass then yes they can be refurbished.

Here's a boot lid light shroud from a Mk IX that I've had up on eBay for the past year or so at a silly price
https://www.ebay.co.uk/itm/Jaguar-Mk-VI ... 3790239302

It was put into the re-chromers in a really bad state. To be fair, they did try to take out much of the pitting that was on it, but this was the best they could do and it ended up like this. Unless you've got only one or two marks that you can pass off as "patina", it really doesn't pay to try a rescue something that's badly corroded, no matter how keen the re-chromers are. And that mazak is a horrid "metal" :cry:

Thank you for your valued feedback. Looks like a lot of mazak was used for the small parts, with the real metal left for the bumpers and front grill. I will re chrome these and the rest I will replace.

Thank you again for your insights. Much appreciated.

Hi Clive, for the outside then the mazak items are the door handles, rear number plate plinth, rear light plinths, Jaguar leaper and the boot lock I think. Mazak can be rechromed if not pitted and if the rechromer can polish out the imperfections. Otherwise all other items can be rechromed. Internally there are more mazak items. Talk to a good rechromer as each one has their own view on what they can and cannot do. Also make sure that the rechroming is the full job.

Quite interesting looking up Mazac and the various types and problems, especially Zinc Pest.

Thanks a lot PPV for your insight. It is certainly helpful. My Mazak parts are fairly pitted, so I dare say they have to be replaced. But I will have an expert rechromer have his say first. That said, I will try and keep much of the old parts as I can for value's sake. Thank you for your interest.
