First off, I'll say I'm meticulous about my V and this is why I've noticed this so quickly.
My bike sits outside in the poor weather. (I'd get it a hotel room if I could.) I live in dorms and there's nowhere to store my bike safely or under 100% cover. There's a overhang but on weekends that same area is occupied by drunk people getting too wasted to be anywhere near my V.
The bike is covered just about 100% of the time though with a good Covermax.
I noticed, however, that after this past weekend's massive thunderstorms that there are faint ammounts of rust colored areas near the edges of the 'inner' part of my front brake disc, it's not on the actual braking area itself, but I don't care. It needs to be gone! And not come back.
Any tips, comments, suggestions, or otherwise? Seriously, I'm starting to consider that hotel room.
