Foamy

I stupidly ran my front wheel against a high curb and scratched up the rim.
I filed off the worst aluminium nicks and sanded the scuffs, but it still looks bad espescially where the anodised aluminium has scratched.
Anyone know if there is a "Magic" solution to make this damage look better ?
Wheels are as supplied with the vehicle 2004, RX8 AT wi :o th sports package (18" wheels).
