Also looking at a 570s - late 2019

I asked as about panel condition and got this response :

No bubbling on car , warranty work on corrosion was done when we took into stock. Front bonnet, wings, door appliques.

From what I have understood from this thread it is likely to return / appear elsewhere?

Do we know how / why it occurs and anything that can be done to minimise occurrence?

Did you watch the video about 4 posts up the page ?

Yep twice !

So the first question is answered in Thorney's video. Aluminium is more reactive than steel, so when painting an aluminium panel, the first coat of paint (the primer) has to have a stabilising agent mixed into it, to prevent (I assume oxidation) reaction of the aluminium with the paint. The occurrence of corrosion on Sports Series McLarens suggests to Thorney that the factory failed to use the right stabiliser, or enough of it.

It's notable that other alloy-panelled cars, like the AM V8 Vantage, also seem to suffer corrosion issues.


The second question is whether, when a car goes back to McLaren and they replace and/or repaint the panel, they use adequate stabiliser for the repair, such that this same problem won't recur. That isn't answered on the video.

So question for owners, has anyone had corrosion recur on a panel which has been repaired by McLaren?


The other factor is that even if the repairs are a permanent fix, any given car is likely to have had only some panels repainted, so the car may suffer further corrosion on other panels.

Polished alloy McLaren, anyone?

I was told by the Mclaren approved bodyshop where my car went for warranty work, if you have a panel replaced there is a 3 year warranty on that panel and a year on a repair.

From my expereince this year, it would seem they are keen to repair rather than replace, maybe this is their new way forward for claims.

There is logic to the repair mentality; as inferred they always corrode in the same place, even replaced panels suffer, so correctly repaired panels might be the better option.

My 68 reg 570S, owned by me from new, has not had any bodywork issues to date.. Hopefully I am not tempting fate!
