Rust around Discs
I have noticed that there is a lot of rust around the outside of all 4 discs. It seems to get to a point and then stop, so I'm not worried from a safety point of view, but it doesn't look too nice.
If I clean off all the excess rust and paint the outsides with some anti-rust paint, will this be ok? Will it actually prevent rusting, or are there stronger forces at work here?
