Wheel arches surface corrosion on a Cayman...

[T1547]

Hi
I wondered if anyone had any suggestions as to the best way to address this/make good please. I wasn't sure if this could be corrected by myself with wire brush and touch up pen, or if it would be a job for a detailer, smart repairer or needs a body shop?

Apart from these two spots on each front wheel arch the body and paintwork is in good condition.

Thanks for any advice.

I've fixed this on both of my porches . Put some hammerite rust remover on a kitchen towel and stick it to the rust. Keep topping it up for a few days so it stays wet. Then once all rust is gone wire wool to key up the surface. Then grey primer. Then get a pot of your paint colour from eBay and apply thin even brush strokes. Looks like-new .

Thanks very much for the advice. That was just the information I was looking for.

You also need to get the wheel arch liner off and deal with any rust that has gone around the back of the panel.

No point only fixing half the problem as the rust will be back..

Agree with that. I'd be getting down to bare metal and then building back from there.

I saw it on a 997 GT3 --- isn't this poor design on the part of P ??

Whatever happened to underseal beneath the paint in exposed areas ?

What sort of mileage and the age of the car.

I've made a set of rubber mudflaps for mine as I was sick of all the stones chips down the sides they are not pretty but it's now basically stopped this from happening.
