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.

Remap to 181.9hp and 300.7 Nm £354.
Private Plate RCZ 2820 (£365)
Cleaning Kit Bits (£400+)
Recaro Car Seat Protector £22.50 (for the dog)

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.
