This is what I think the problem is, especially with mine. I have read they are anodised, and it seems the corrosion is happening under this hard coat.

I know that sounds impossible, but I have tried various methods, even used Autosol with a buffing pad on a drill to try and remove the marks but nothing changes. Here is a close up pic to show what I mean.

This is exactly what mine look like.

Yesterday I decided to give the arches another go.I found that G3 Professional Scratch Remover did a marvellous job in ridding all water marks etc.

It's much kinder than T cut but still does the job without damage and has left a super shiney surface.

How I can keep it like that I don't know ,but it didn't need much elbow grease to clean the surface so not too much a job to do it every time I wash the Z (which admittedly isn't that often!)

It's Liquid and is like a cream.

I used the paste with the same brand applicator pads and found the result was excellent - thanks for the tip! (I've tried AutoGlym and Dodojuice products and the G3 was much, much better!)

Next question - now my arches are better... can they be 'sealed' in the same way as paintwork?

Any suggestions would be much appreciated.

Yes Definitely, loads of products on the market to seal the arches most ceramic coatings will do the job I prefer soft99 products but the choice is endless. :thumbup:

Hi
This did a pretty good job of cleaning the white spots from the arches of my RCZ and leaves a protective film.

From my research: The arches are made from anodised aluminium so abrasive polishes or pastes (and some chemicals) remove the protective coating, leaving them exposed to oxidisation (aka rust - aluminium rust is

Happy motoring

Just tried the Autosol anodised aluminium polish and it didn't work in my situation.
I have used Autosol metal polish on other products before but this was totally different. It seems to be more of a gel that you leave on and then wipe off with a damp cloth (no rubbing/buffing).

It looked good when applied, and got my hopes up, but went back to white spots after drying. See photos.

This side didnt receive any treatment and has been untouched since it's wax coat last year.

This is the treated side.

I wiped the arches down with a damp cloth to clean off any dirt etc. so I don't think the wax coat would interfere.

I left the gel/polish on for about 20 minutes as the instructions lack specific detail. If you know of a better way to use the product let me know.

As I have mentioned, I believe the corrosion is "under" the hard coat of anodising, so nothing will have an effect unless you can get under it.

Well, I have finally managed to fix the silver arches problem once and for all.

After DKZ5745 & 2retro mentioned Plasti dip in the "Replacing mk 1 front end badge" thread, I went down the rabbit hole!

I didnt used plasti dip though, but their European counterpart that is supposed to be a slight improvement on it, (I can't comment or compare that claim).

Those arches look great, OkeyStokey. :thumbup:

I've thought for a long while about getting mine either wrapped or having a go myself with Plasti-Dip. Yours have come out really well so it's making me want to do mine too now! Any tips on masking up, etc. to share? I would have to do mine outside though and it's probably going to rain every day until May 2020 now but on the off-chance it's dry and mild at some point I'm definitely tempted...

Well wrapping was going to be around £100-£150 from the one quote I got, and this can of vinyl was £9.99 delivered, so a no brainer really.

The masking (prep) takes most of the time. I would say you would need about 1-2 hours in total. I managed 3 coats with one can, though I think 5 coats is optimal.

I bought the 3M masking tape (blue colour) as it is supposed to be waterproof, which I thought might help stop any bleed.
Luckily, the arch has a black rubber seal all around, so spraying onto this doesnt show either.

The spray is very easy to build up and cause runs, especially if you spray from left to right and back again.
So my advice would be to spray in one direction along the length of the arch, then back again but lower to try and keep coverage uniform.

The beauty though is that if you make a mistake, it just peels off and you can try again (whilst it is still soft).

When dried, be careful removing the tape, it will try and peel off as one in some places.
I found taking your time and watching where the tape breaks away means you can catch it before you remove too much vinyl. A spudger or plastic edge/blade can then be used to cut it off the tape.

I seem to remember something about there being one agent that supplies to each country. Could be wrong, but I got mine from eBay, item number 333151384607. They do both types if you want the US one.
