911 GT3/RS wheel nut paint damage

[320]

Hi
Anyone else experience paint coming off the centre nuts on the above? Used a non acid cleaner and major damage only to the centre nuts not the wheels.

Shame that, What did you use?
I’ve just traded my 718CS for a 991.2 GTS and wouldn’t want to do the same.

I used a non acid wheel cleaner and a jet wash, wheels are fine just the centre locks, gutted

This is a common problem. The 600nm needed to remove/refit wheels seems to be beyond what any paint can stand. Centre locks look great when new but removal of the wheel (and/or aggressive wheel cleaners) can wreck the centre bolts. My ones are, luckily, bare metal so I clean then carefully with steel wool and a dremel. Personally I’d give up trying to keep the paint intact and take them back to the shine of bare metal.

Thanks Chubby Ross
The issue is the wheels are satin black and will look awful with a steel centre. Thanks for the feedback. I am shocked to realise it’s a known issue. The car was mint before. 😢

I've always used Super Muc Off bicycle cleaner, works well with no problem whatsoever .

They’re anodised not painted aren’t they?

Yes, so the chemicals in the wheel cleaner have reacted (bleached probably) the dye used in the anodising

[320]

I simply assumed you could just clean them like any other wheel on any other car but clearly this isn’t the case. They are ruined

[arcamalpha]

Ouch. That must have been a strong wheel cleaner. Didn’t have that with mine.

New nuts are about £600 I think or you could try getting them re-anodised I guess.

[Chubbyross]

That’s horrendous! What wheel cleaner was used?

[rbh]

I've used indelible black magic marker on any minor areas which although not perfect is pretty good

They are anodised and they can get damaged when tightening/loosening the nut. Once they're damaged general cleaning/use will make them deteriorate pretty quickly.

I had mine re-anodised and they came up really well, you'll lose the writing which is a shame but it cost around £120 to get all 4 done on my 997 GTS.

I used non acidic black frog wheel cleaner. I like the anodised idea. Porsche are looking at it and will let me know. Fingers crossed

[short-shift]

Hate to point it out but it looks as though the disc/hub bells are marked and stained too...

That must have one heck of a cleaner. All the damage done in one wash??

If you do get then re-anodised in black, it would be great if you could post-up some pictures afterwards.

I remember researching quite a few of the wheel cleaners currently on the market and many of them do cause problems on black paint, especially when allowed to dry. I’m guessing you probably did dry yours but excess liquid was flung from out of the centre cap when on the move. This then dried and did the damage.

Damn, sorry to see that picture. Does the cleaner say what chemicals are in it? Some of the non-acidic cleaners use caustic soda which will dissolve the ali oxide containing the dye.

I’ve worried about this happening, so I didn’t take any chances and went for the best wheel cleaner I could find, and made sure it was PH neutral.

Been using this for a year now on a 991.2 GTS with black centre lock wheels.

In fact, all my cleaning products are gyeon, recommended by topaz after I had my ppf done.

I use autoglym custom wheel cleaner on my black 991.2 GTS wheels. With g.techniq iron/fallout remover once every few months. My centrelocks still look like new after a year/6k miles.
