I was giving my Giant a polish up the other day and I noticed what looked like a couple of "rust bubbles" in the paintwork, on the seat tube and more on the top tube. I was able to scratch off the paint easily and along with it the white corroded aluminium. The corrosion wasn't deep, doesn't look critical, but makes me wonder how it occured and how I should treat the bare metal now?
Is this an electrostactic thing? Electrolisis? What do you people think I should do to treat the bare metal?
