If you have photos, that could be helpful, but often paint polishes work -- such as Mothers California Gold Scratch Remover, which works great on wheel coatings.
Brake dust can often eat into wheel coatings, and it takes a polish to remove them.
Wax frequently with something like our California Gold Synthetic Wax, and/or California Gold Spray Wax.
Thank you for using Mothers!
Sincerely,
Jim
