DIY Road Rash Fix on my Rims - some help please

[MrAstro]

I have some Alloy Rims on my car - a Golf 90TSI Mk7 and I glanced the gutter and road rashed them.

So I did my best to repair them by going through the grades of wet and dry (up to 2000 grit) and then I used some metal polish (Autosol).

As you can see there are some lines which you can't feel with your finger and the contour looks reasonable from an angle.

I was hoping some of you might have some experience in what's going on here and maybe I can have some advice about what to do next... I intend to hit them with some rattle can clear coat on the repaired area to stop oxidisation but I'd like to understand why I have visible lines on the metal. One is up near the bead of the rim and one is half way down the spoke ie. between the hub and the rim.
