355 Alloy Blistering??

[swb1]

Hi All,

Hope someone can help me.
I had my original 355 alloys refurbed about a year ago and all good as far as I could see. I store the car in a classic car warehouse and have just had the car cleaned and detailed by their recommended company.
On inspection though my rear alloys are ruined!!
I want to get others opinions to the cause and what the hell I can do? Someone who had more experience with Magnesium wheels and recommend anyone for a top job?? Heres the damage:



Thanks in advance

Matt

Were they not refurbished properly as they are magnesium- did the company know they were magnesium? Or was the wrong cleaning product used on them? Who detailed the car?
I would ask both questions.

Thanks for the suggestions.
Ill have to contact the refurb company and the detailers.
I think the fronts still look on but will have to check closely.
If the fronts are ok, either they werent cleaned or refubed differently. Do you think?

Thanks

All other feedback would be most appreciated, I know nothing about magnesium wheels!!

Thanks

These wheels are notoriously difficult to refurb and that looks to me like a reaction under the paint rather than 'damage' by the detailer. I've seen several sets with the same defect which appears after time.

What were they like prior to refurb and ask refurbisher ffor the process these use for magnesium wheels then post back.

Can highly recommend TPCS Ltd (Turners Powder Coating Services) in Melksham - see website.
Experienced with Ferrari Magnesium wheels and associated problems - they did my 355 rears early this year and proved helpful, understanding and efficient and sent regular photographic evidence of each stage in the process of the refurb. Steve Turner was happy to discuss the procedure after I sent a pic of the wheels - similar corrosion marks as yours only around the rims rather than the spokes.
Only problem is that they could not finish in the correct silver colour but a straightforward respray by a local bodyshop without further undue heating sorted that out and they are as new again.
I had no previous knowledge of this company but they were suggested to me by Ferrari approved bodyshop who were reluctant to undertake the repairs themselves!

Agreed, I suspect the wheels were left unsealed during the process allowing moisture in which ha then been sealed in by the paint. I'd get them looked at by somebody who knows how to deal with magnesium wheels they can easily become scrap if left

OP's problem will be finding someone to do them - ever fewer remain who are prepared to look at 355 wheels - I can't recall the last viable recommendation

The wheels were fine before the car was detailed on Wednesday, so happend fairly instantly and maybe the detailer would have seen it happen there and then so didnt touch the fronts? Ill have to try and find out but who can say ill ge tthe facts.
(About 12 months old refurbishment)

Is it the type of cleaner used or not done correctly?

Do Ferrari still use Magnesium wheels or was the 355 the last???
How do modern Ferrari's get their wheels done??

Exactly. The detailer owes you some money. Now you have the task of getting them refurbed.

From my experience, these things can happen with magnesium wheels overnight whether it's the day after being refurbished or in 6 months, there isn't a fixed time - I doubt that anything the detailer used could cause the blistering.
