Ok, I've picked your brains about the rust, now how about these wheels?
I want to sand and repaint the little trapezoid-shaped areas of rust. They're a result of these wheel covers:
The problem is the rest of the damage/rust/embedded brake dust on the wheel. I've used Eagle 1 A2Z on the tires and wheels to get rid of the worst of it. The tires look 200% better now, but I can't seem to break down that brown residue on the wheels, especially in the recessed groove around the edge. A lot of it was broken up with a coarse spoke brush agitating the A2Z (look at the wheel center around the lugs- you can clearly see where the brush didn't get), and then going to the car shampoo, but I'd like to get in that groove to get them totally clean before I sand and repaint the problem spots (I'll likely just sand the rust off, rough up the rest of the area around the holes and repaint just that with some Krylon RustTough gloss black). I think a wire brush would just make things worse by being too abrasive and stripping the actual paint off. Any ideas? Am I totally OCD?
