Rust on bonnet?

[phillcom3]

I got to my car today at work and saw an orenge dot it came of with my fingertip so didn't think anymore about it. Then 10 mins later had the chance to look again I saw a few more dots so I thought has somthing splashed me which wouldn't supprise me at my work.
Then whilst driving home I was like wait wtf I can't be having pitting on my bonnet it's ceramic coated....

So I took a picture which I hope has attached and cleaned the bonnet with some Maguires waterless.
If I see orenge back again I'm going to have to make an apointment and check the paint for pitting.
Any advice for the argument I'm bound to have?

To make maters worse this car has been ceramic coated so Durley should t be able to get oxygen through paint even if it had a slight pinpric?

Could be iron fallout from brake discs etc. Try some fallout remover e.g. Gtechniq - W6 Iron & Fallout Remover

Isn't the bonnet aluminum and rust proof?

Well the boot isn’t despite reports as a magnetic GB badge sticks on

Are you seeing what's below the colour due to the paint being very thin.

On a few occasions, I have seen an orange maybe golden tinge to the paint, even though it is meant to be blue. I just assumed that this was what was below the colour showing through in extreme lighting conditions.

Yes, it’s iron fallout. I had some. Iron X spray or similar or a quick rub with a clay bar will sort it. It’s on top of the Ceramic by all accounts.

Guys it was a few well a lot of orenge spots could be fallout like one suggested as it was gone and couldn't feel a pinprick after a maguares waterless. I think being near an airfield and the rain constantly on it isn't helping. So I'll keep my eyes out and update as appropriate

Don't think M3 has much aluminium in it.

More than 'not much' - chassis mix Tesla Model 3 Blending Steel & Aluminum — More Details | CleanTechnica

And bonnet is definitely aluminium (except the badge!) hence reason why care is needed to close. Looks like bodywork wise, its bonnet and doors.

@M3BlueGeorgia disagrees with my comment that the M3 doesn't have much aluminium in it - I'll concede that to a point but it has substantially less aluminium in its construction than previous Tesla models. Otherwise it would be significantly more expensive to build and insure. The bonnet (hood) is not steel so is most likely to be aluminium.

Had these marks when I first got the car on the rear

I live close to train tracks, so these things are very familiar to me (and now to my model 3).
