As the title says I have found rust. It is on the upper edge of each front wheel arch.
I have no idea what to do, is it just a case of grinding it down, filling, smoothing and painting, or will I need new arches?
Here are some pics.
The first one is of the passenger wheel arch, where the paint is only bubbling slightly.
The last 3 are of the driver’s side arch, and as you can see it is a lot worse.
Excuse the water marks I haven't had a chance to clean the car since the weekend.
