anyone have info/tips on repairing curbed wheels?

I have 2 wheels w/ moderately bad scuff/curb scratches. What would the best way to repair them myself?

i was thinking, could I use bondo/bondo-glass on them?

or is there some way to repair it w/ metal working?

or should I break down and just sand the curbed spokes down? this is my biggest concern because not every spoke is curbed, so I'm afraid sanding down the spoke would throw the wheel balance waaay off?

 

sand it with 500 grit then 900 grit sand paper after that use some metal polish to buff it out...
