Hey guys 'n dolls

Out of some reason that would take too long to explain, I found out that =
there
is RUST inside the rear-rim of my beloved RD03. Most of the corrosion is =
around
the tube-valve hole! (that 's where the dirt gets inside) Has anyone =
seen such
thing before? I removed as much as possible and it was quite a shocking =
view -
at some places the corrosion is about half a millimeter deep, and it =
fell of
like dust at the surface. So what can be done about it - should I just =
leave it
or put some varnish or rust spray or so on it?

keep up the @ spirit

I have a similar, but different (is this possible?) problem with my '96 =
RD07. The rear wheel rim is covered with corrosion pits on the brake =
disc side. There is no corrosion at all on the chain side or the front =
wheel, so I am wondering if it is caused by particles of brake pad / =
disc that are deposited during braking onto the aluminium surface - then =
some sort of electrolytic corrosion is forming. Anyway, it looks quite =
bad and I am wondering if any fellow @'ers have experienced this.
