Hard wearing metal paint

[Grahamm]

Just be careful about glueing old bike inner tube Graham - outside of the confines of the tyre, inner tube rubber rubber oxidises hardens in daylight/sunlight and loses its elasticity, then it cracks and breaks apart. It can be really messy to remove if you use something like Super Glue (don't ask me how I know  ).

I wouldn't actually glue the inner tube to the rack, but I could split it in half and wrap it around, then eg tape it.
