When I tipped my bike over, I scratched the powder coating on the frame. How can I repair the damage?

Scratches in the surface can be polished out with paint cleaner or polish and a cloth or polishing cotton. A drill into which you clamp a polishing disc will speed up the work. If the scratch is deeper, you should seal the area to prevent moisture from penetrating and causing corrosion. Touch-up pens, such as those offered for car paints, are suitable for touching up. If none of the standard colours match, you can have the colour mixed at a specialist dealer.
