The frame of my Urban Arrow Family Anniversary edition seems to be damaged of corodization, what can I do?

The frame of the Urban Arrow Anniversary is uncoated Aluminum and will corodize in time if you don't polish it. This corodization does not harm the frame.

You can remove spots and make it nice and shine again by:

- Cleaning a damaged spot with WD 40 or other suitable cleaner.

- Sand out scratches with 3M Waterproof Sandpaper grit 1200 (be aware to avoid flat spots on tubes)

- Initial finish with 3M 07904 Scotch-Brite finishing pads Grey (rub the pad in the direction of the brushing)

- Final finish with 3M 07903 Scotch-Brite finishing pads Purple (rub the pad in the direction of the brushing)
