Rust on wheel hubs - concerning or not?

[TB]

I swapped my wheels front/back today to even out the tyre wear. (The dealer who serviced it last month apparently didn't think to do so [bighmmm])

Below is what all four of my hubs look like. Should I be concerned and get this treated somehow?

Spray them with something if you want, but , no, you'd have found that if you'd taken the wheel off the day you picked it up. They all do it. By all, I mean all cars, not all LRs.

Yep, totally normal. Brake disks always have surface rust. Nothing to worry about.
