Hello, I not too long ago built up phil/openpro front wheel for my winter riding. It has been exposed to months of all-weather riding conditions, -rain, snow, salt etc . . and I have noticed that the steel separator between the (red) dust cap and the chrome (machined aluminium) hub body has rust . . I am thinking (hoping) that the rust will actually protect and help prevent any further corrosion.. Is this going to be a problem? Should I sweat it?
