  1. My model of MX-5 is: __RF 2.0 2017 Ceramic Metallic
  2. I’m based near: __Stockport
  3. I’m looking for technical help or recommendations on: Wheel discolouration
    On one of my Alloys there has developed an area of. Dark Grey a sort matt patch which is odd as the others are fine. Anyone come across this?

Have you washed them with an acidic wheel cleaner and forgot to wash one of the wheels off? That may have compromised the paint if so.

Do you have a photo you can post, to show us?

Thanks for your responses. No, I’m very thorough when cleaning so wouldn’t have not rinsed off. Difficult to see in picture.

Maybe easier to see if you also take a pic of a ‘good’ wheel? Or highlight the patch you’re concerned about.

Good area of wheel to compare

Also a photo showing the whole wheel, with the discoloured area on it? It’s quite hard to get context from just one close-up.

Looks like maybe the laquer has failed or been removed, leaving only the bare paint? Don’t suppose you’ve been polishing them with something abrasive?

I’d never do that John. Occasionally I will use an alloy wheel cleaner but mainly stick to the same car foam cleaner as I use on the body and always a lambswool mitt which it’s why it’s a mystery.

Sure. Not trying to accuse you of anything. Just clutching at straws really. :man_shrugging:

Does it feel like a ‘high point’ on the wheel? Can you feel any difference in texture when you pass over it?

My NC had the same problem . Laquer just come off . Had my powder coated in gun metal.

Ah. Good ol’ Mazda paint quality/thickness :scream:
