Loss of paint on aluminium frame.

On my frame some of the paint has come off, I think it got scratched and being near the bottom bracket water has seeped in and flaked some of the paint off.

Is this anything to worry about. I think Aluminium gets a thin layer of oxidised aluminium on its surface when exposed to the air which protects the rest from rusting so it should be ok, but I just thought I would check.

Also; if I wanted to patch it up what kind of paint should I use? It's a black frame so matching the colour isn't that important.

    You won't have a problem with corrosion for the reason you state. My frame is mainly black and I use Humbrol model paint or Hammerite for paint chips.
  • I used nail varnish for small chips.
    There's no such thing as too old.

    I prefer salt & vineger.

    Toy shop model paint is good for touch-ups.
    I even used this paint on the top caps of some scratched up Tiagra shifters and they finished off really nice. It also allowed me to match the bar tape colour.
