The way silver wheels are made is either 1) silver powdercoat or 2) silver paint with clear powdercoat over the top. Paint without a protective coating is not very durable. If you youtube "rays forged wheels" there's a video that shows how they forge, heat cure and powder coat. Any type of touch up paint will just covering be up the marks that have went through the thick protective coating. The only way to feally "fix" it is through "wheel refinishing", where they strip the coating, sand blast the wheel, repaint it and apply new clear coat. Lot's of companies offer this and will run $200-250 a wheel.

If I didn't point it out to people, they didn't notice. Even pointing out the repair, you really couldn't see it. It is one of the harder colors to repair though.
